I love the update. Here are my initial thoughts:
- Tons of little refinements throughout the OS not many people are talking about.
- App store icons load MUCH quicker over 3G, and no longer get "skip apps". A huge bug in 2.X that was rarely talked about. Glad it's fixed.
- Once you select an App, images at the bottom are now all available to see instantly. You no longer need to select the picture to view it. It loads as you select the App and are available to view instantly.
- OS seems snappier.
- GMaps picks up my location MUCH MUCH quicker. Instantaneous....bravo.
- Widescreen typing is awesome, as expected, and feels better in 3.0, than in 2.X.
- Safari loads webpages in WiFi faster. Less hiccups. 3G is about as fast as it was before, possibly a little quicker.
- A site like Dailytech.com, which had slow rendering times in 2.X, renders rather quickly in 3.0.
- Missed calls now show where the call came from on the missed calls list itself.
- If you click on a previously made call, it shows you how long the call was in talk time (not sure if this is new, but I don't remember this)
Lots of more things to go over, but those are my experiences so far.
