So what do people think as far future major updates go on how long in between updates?

I am thinking that HP / Palm will probably go to a 6 month update cycle. That is what everyone, but Apple are going to. Microsoft is releasing their first update after about 6 months on the market. Kind of major update. The last major update for webOS was 2.0 and if released to all devices would have been about 7 months since 1.4.5 was released. The first major update for the Pre 2's will probably be this summer (June ish) about the time the Pre 3 is released and possibly for the Veer as well. There after the next one I am thinking Novemeber ish to bring everything up to 3.1.
