So, I 'blindly' hit the 'update to 4.2' option, went through the OS upgrade, and am now regretting it. Not for reasons of 'aesthetics' (although I think the new clock app is fugly, and poorly designed. I absolutely *hate* the new clock), but because of significant system instability. A number of examples, but here are the key ones. 1\ tablet new reboots itself, often 2-3 times a day. More or less randomly, more frequently if 'waking it up'. This is the big one for me...if this was one of my *man* desktop systems, I'd format the drive and start over. 2\ location of widgets and various bookmarks seems to move randomly (today, I found that half had moved to one homescreen, half to another). 3\ typing isn't as 'precise' as it once one - now, new characters seem to toss themselves randomly into the mix. 4\ battery life is shorter. Same apps, same environment, but with 4.2, instead of 4.1.2. Alas, I'm not particularly impressed by 4.2. The usual explanation is 'not a bad OS, its a bad app'. Well, issue (1) (above) occurs even if I unload all my apps, except for the 'Google' apps. I don't have that many apps (15-20) so that performing this little experiment didn't make much effort. Results? Its the OS, not the apps.
