Thanks for the heads up. If you could use the capacitive buttons and get rid of the navigation bar like with ICS, I would update.
I do not want to lose the screen space, so will pass. The Acer 100 7" looks cramp to me, with HC.
BTW, I got an update yesterday, but was only 27mb, so went ahead and updated. A HC update would be a LOT bigger than 27mb.
I have the Flyer and View and both are staying with GB. Both work great and faster than my Thrive that does have HC.
