I beg to differ. Gingerbread brings a lot of bug fixes under the hood. My N1 feels more snappier and less prone to random reboots with Gingerbread than Froyo. It's inexcuseable for carriers and OEMs for shipping a new Android phone today with Froyo, considering Gingerbread has been out since December 2010. Heck, Ice Cream is coming out in Q3 2011.
I was reading a lot of the OEM were going to skip Gingerbread completely and just go to Ice Cream. Reason for it is Ice Cream is bringing a lot more to the table than Gingerbread. Namely better support for dual core phones and allow HoneyComb apps to run on it the android 2.x line.
Honeycomb table design.What happened to Honeycomb?
Basically 3.x is tablet and 2.x is phone.
