Sony VAIO SVD13215PX 13.3-Inch Laptop

Why I bought it in the first place?

Being a full time IT professional, and a full time CS student, a hybrid laptop with a digital pen for note taking seemed to be the ideal choice.

So here are the needs I thought the Duo 13 could fill:

  • Digital Note Taking (Both in Class and at work)
  • Some light Java and Python Coding
  • portability
  • long lasting battery life (9+ hours)
  • maybe some light gaming (the likes of hearthstone, hex, etc)

And for USD 1,800 (~ KD 500) I thought I was set, so I ignored my alarmed gut instinct and went ahead with the purchase.

Boy was I in for a surprise…

The Duo 13 Experience!

Digital Note Taking

While many will argue that digital note taking on this tablet is fine… I sincerely disagree. The Duo 13 uses the Ntrig (Duosense 2 dual digitizer 13.3 @1920×1080).

While researching its note taking capabilities, I’ve gotten the impression from other users that this is fine. I’m here to tell you otherwise, it is “Certainly” not fine!

I was aware that you could not stow the pen in the tablet, and I was fine with that, cause I would just slide the pen into my messenger bags pen slot.

The clip they try to sell you on however, that was a total joke. The clip will often disconnect, and your likely to lose your pen, so best that you don’t depend on it.

As for note taking, when taking notes in class, and your ntrig digitizer fails for some unknown reason, you do not have the luxury to ask your professor to “pause” the lecture until you’ve sorted out your technical issues. In this case, restarting the Duo 13 would solve this, only for it to randomly happen again when you least expect it. And I promise this sudden and unpredictable failure will happen often, at least once in every class or meeting.

As for handwriting recognition, try playing an MIT lecture on another device, and take notes (freehand) on the duo 13, then ask One Note to convert to text. Now tell me, are your notes still usable?

No they wont be, because you’ll have to go back and spend another 45 minutes re-formatting your notes so that its not just a wall of text. You’ll also have to correct the spelling and false word recognition due to your shoddy handwriting.

Your notes will often include a mix of text, numbers, diagrams, special characters. Those of you who take discrete math or any advanced science course will know what I’m talking about.

So ultimately the question is: Can I use the Duo 13 as reliable Note Taking tool.

No you cannot, don’t fool yourself, go buy a real Ultrabook, skip the note taking illusion, we’re no where near it today. (Probably why Apple hasn’t built it yet.)

Two in One Hybrid Design

The Display

When I first looked at the amazon listing, looked at the pictures, I knew the slide out display design was not going to work. But I kept an open mind and decided I’d give it a shot, maybe I was wrong.

Turns out I wasn’t wrong. While it may seem cool and appealing, in reality its very counter-productive.

Once you slide out the screen, it locks into a fixed X angle. This is not adjustable.

So you why is this so horrible? Well the display is glossy and will reflect practically any light source, office lighting, etc.

Usually people tolerate the glare because they adjust the angle so that their own reflection (or person) blocks out the pesky neon office lights.

This is usually done by adjusting ones posture and angling the display towards oneself. Problem Solved.

Forget about doing this on the Duo 13, the display is only great in soft lit rooms, and how many of those will you find in the office or in college?

To be fair, in tablet mode this is much less of an issue obviously. However, I use tablet mode exclusively for taking notes, and in this case ntrig has failed me once again.

Its important to note, once the novelty of a touchscreen has worn off, you will only use the touch screen for the following:

  • Windows 8 calculator app
  • Scrolling while browsing the web

In my opinion the UIX for windows 8 touchscreen devices is horrible. This includes 8.1, and I strongly believe that Microsoft needs to can this entire windows 8 design, and start from scratch. And hopefully they’ll have the common sense not to force the touch interface on devices that have a keyboard and mouse. Despite having used windows 8 and 8.1 as a daily OS, I’m still not convinced. Windows 7 was bad, but windows 8 UIX is even worse if that’s even possible.


I’m a touch typist, and to be honest.. I think Sony did an excellent job with the keyboard. Its soft, responsive, and reliable. The short travel distance is something that I adjusted too over the course of a week or so. You’ll end up appreciating the idea of not having to punch the keys so hard to type something. If only Apple gave us the option for short travel keyboards….

However … there is one big caveat, the track pad. Its a narrow strip bellow the space bar, pushed to the right a little bit. Your thumbs will often brush the pad and move the cursor to some random place in your document whilst your typing. Very very annoying, so far, typing this article alone it must have happened at least 4 times. Which brings us to the next point…

The Trackpad

Somewhere (forgot who) someone said it best. At best its a very “crude” tool to move the cursor around. No exaggeration really. When you first test it out, you will think to yourself hmm… I could live with this .. its not too bad. Haha! You will hate it by your 3 month of active use. Its just horrible. Mainly cause its too narrow measuring a depth of 1″ (2.5cm) by length of x” (8cm). Length wise its fine, but the depth is horrid. So even for mainly a text editing task such as writing this post, I do in fact have an external mouse attacked. This leads me to believe that the engineers assumed users would simply use the actual display as a trackpad. This approach doesn’t work very well with plenty of non touch friendly apps.

Duo 13 ports

All the ports are placed on the back of the Duo 13 DC, 3.5m audio jack, 2 x USB 3.0, SD. (Respectively)

Plugging stuff in is very annoying, and you will plug everything in at the office and at home, so that you have enough power to go (attending classes, or at a coffee shop etc..)

Now if you have the screen out, and you need to plug in your mouse, and the DC port, this will frustrate you to no end at least 5 x week.

Just visualize this for a moment:

  1. Lift or angle tablet upwards
  2. Plug in DC and USB mouse
  3. Angle tablet back to surface, while carefully avoiding placing your laptop on the DC  or USB cable

Now imagine doing this at least 5 times a week.

Transport / Sleep Mode

Now this is very critical, isn’t it fair to say, that most of us put our mobile devices (ultraboooks, tablets, etc) to sleep when were on the move? When you get to your next work place which may not have to be on the same day, you just flip open the display and expect to be ready to work or play right? Not with the DUO 13.

Sure you can put it to sleep, but I guarantee you it will “wake up” while its stowed in your messenger bag or whatever you use to transport it.

The side power button will wake it, and the windows hardware button on the front of the display will wake it too if its pressed.

Due to this flaw, I’ve always had to shutdown the Duo 13 every time I moved location. Which is annoyed me to no end.


I realize this is not a gaming tablet, however despite this I had no issues playing HEX ( If your into collectible card games like Magic the Gathering Online you might want to check out hex or hearthstone. I haven’t tried HS on the Duo 13, but I would expect it to run, and if not, I could always play Hex instead.

Security – Fast Access

Ok its a given face unlock is not secure on most devices. I’m not about to bash on that. Lets discuss something much more serious, Fast Access will unlock your tablet even if it cannot recognize your:

  • Face
  • Password
  • Unlock Pattern
  • Does not stay in sleep mode
  • Horrible Trackpad

Just keep trying, and eventually voila, it unlocks and grants full access. Now that’s just retarded. My advice is to uninstall it ASAP, just login with your password. If you plan on using face unlock, be prepared to sit up and over the display, while hovering an inch above your chair so that the camera can see you. Which is also annoying if you plan to use facelock as minor access deterrent.


The bottom line.. for the same money, you can get a much better ultrabook. Be it windows or mac.

This is certainly a white elephant!


  • More expensive than the rMBP with weaker specs
  • Cannot be used to take digital notes (uses Ntrig)
  • Display has too much glare (cant adjust screen angle)
  • Bundled Software is crap
  • Fast Access is not secure enough even for people with light security requirements
  • certainly a white elephant


  • Its as light as a Macbook Air (2.9lbs)
  • Excellent keyboard
