Sony's tablet a good idea gone wrong<br>
PUBLISHED: 30 Mar 2012<br>
<br>
The best thing that can be said about Sony's new $729 Tablet P is that<br>
it means well.<br>
<br>
The central idea that must have led to the construction of the Tablet<br>
P -- that iPads are too large -- is pretty sound. iPads are too large,<br>
at least for a lot of users (the staff here at the Digital Life Labs<br>
included), and at least for a lot of applications.<br>
<br>
So, yes, Sony was trying to solve a genuine problem when it came up<br>
with the Tablet P, a tablet that folds in half so you can slip it into<br>
your pocket or purse, that's light enough to read e-books on<br>
for hours without your hand cramping, and small enough that you can<br>
use it as a camera without looking like a total tool.<br>
<br>
The trouble was, they couldn't make it happen, not with<br>
today's technology. To have a tablet fold in two, you either need one<br>
screen that folds in two, or you need two screens with absolutely no<br>
bezel, so that one screen blends seamlessly with the other screen when<br>
they're placed side by side. Neither of those technologies are<br>
available today, so all Sony's engineers could come up with was two<br>
screens, each with a modest 4 mm bezel that, when placed next to the<br>
other bezel, creates a whopping great 9 mm-wide black bar right in the<br>
middle of the display. (The other millimetre is the gap between the<br>
displays, which can be quite irritating if there's light behind the<br>
display, shining through.)<br>
<br>
Now, that wouldn't be completely fatal if the Tablet P were running an<br>
operating system that knew how to handle two screens with a black bar<br>
and a sliver of light in the middle of them. But the Tablet P is<br>
running Android, and neither Android nor most Android apps have a clue<br>
how to use the dual display.<br>
<br>
Some apps on the Tablet P, chiefly the ones Sony has rewritten<br>
specifically for the device, work quite well. The email app, for<br>
instance, uses one screen as a virtual keyboard, and the other screen<br>
as a display, when you're creating emails. When you're viewing emails,<br>
one screen is used to list the items in the inbox, and the other<br>
screen is used to preview the highlighted item.<br>
<br>
But trouble arises when you use apps other than the ones written to<br>
cope with the black bar. Most apps will just curl up into a ball and<br>
display only on one of the two screens. Neither of those screens is<br>
very large, so you end up with apps displaying little bigger than they<br>
would on a mobile phone. Worse yet, they're both very long and narrow,<br>
far more so than many apps seem able to cope with, and as a result<br>
many apps won't even fully utilise the one small screen they're<br>
on. Amazon's Kindle app, for instance, an app so well written that it<br>
can usually cope with any screen you throw at it, uses only 83 per<br>
cent of one screen, and zero per cent of the other. Almost 60 per cent<br>
of the Tablet P's display is left blank.<br>
<br>
It's such a pity, because a tablet that folds in two is such a good<br>
idea. Perhaps the best thing that can be said about the Tablet P is<br>
not that it means well, but that it's simply ahead of its time.<br>
