I'll go through the features and give my impression of each:
So now my only gripes are with Google. You can view attachments sent via Gmail, but that's it. No saving, editing, etc. But, I suppose if that's the worst thing, it's still not that bad.
- Video recording capability - Freakin' cool! I've never had a phone that could do that before, so it's a lot of fun to mess with. Not the best quality, but I've also seen worse.
- HTML email for Internet email accounts - I know what this should do, but since I have my mail working with the Gmail app, I'm unaffected by this one. Only thing I'd like Gmail on my phone to do better is to be able to click on embeded links.
- Music and Video Streaming video capabilities - Also freakin' cool. YouTube and other embedded flash video on a phone that's not an iPhone. The quality is pretty crappy (as it is on the iPhone), and it doesn't quite go full screen, but it's spiffy nonetheless.
- New browser home page design - I could take or leave this. Could be good for non-tweakers, but I had my iGoogle page setup for my phone, and it worked perfectly. Luckily you can reconfigure this to your liking.
- Improved downloading experience - Seems quite a bit faster... that's all I can tell.
- Improved UMA and data performance - Definitely faster. Feels like you're on a 3G connection when you're really still on the older EDGE. I'm impressed.
- Attachment downloading and document editing - Downloading good, haven't tried editing yet, but the upgrade did include Word To Go and Slideshow To Go, so it should work.
In conclusion, good work, RIM!
