I installed this past weekend, and right away have noticed two things. Opera 9.5 beta (which I had NO trouble with on the previous version) hangs quite often when launched, be it launched from the hard button, or using the Google search app I have on my home screen. And two, the battery is being eaten alive. I do have third party programs on their, including Seven for email synchronization, but nothing I didn't have before, and yet the batter is going dead halfway through my day. No one else has experienced this?
Truthfully, I've been coveting the Touch Diamond anyway, so this may all be moot, but in the meantime thought I'd share.
