I think in regards t their TV`s, only their high end ones are good. Their lower to mid range sections have always been pretty average.
But on the tablet. I was at the Sony store yesterday (to look at the Vaio C) and saw they had the tablet for use. I checked it out. tbqh...I would so take the Sony over the other Tablets. Its not heavy, the form factor makes for nice grip and the software ran well enough.
I mean, there is nothing that suggests this is worse then any other tablet on the market.. they are pretty much the same save for hardware and slight OS tweaking. To me, Android is Android no matter how you colour it. I have the Sharp Aquos android phone and I am fine with it... I may try the tablet again later today but like I mentioned, I had no problems with an initial hands on and would most likely choose it over the Samsung (which I have also only sent a few minutes with). Prices seem fine in Japan for the device I suppose.
