I got rid of all my AT&T Dookieware© I actually just renamed the .apk files to .durab so it's easily reversible (though I also saved my stock ROM so that's probably redundant.)
The BB is hard to beat as a streamlined business tool for email/contacts. I think Android has a little way to come, but mine works perfect in that capacity when corabined with Google services, like Gmail and Gcalender, however the integration into Outlook isn't the best.
I think the extensibility is also your worst enemy (i.e., don't go app and widget gonzo).
Yeah, I've read there's questionable value with ATK (and any 3rd party task killer). I'll have to check out the current thinking on this again.
I rooted and install the standard Google hotspot app, so I'm able to WiFI tether to multiple devices, using my $30 unlimited data plan and without specifically paying the additional $30 for "tethering". I wonder what will happen with 2.2, since that includes the hotspot app[?] AT&T will probably make their own bungled 2.2 without it (and with their apps).
Honestly I want straight 2.2, no blur/wiz/sense bullshit. I'll add my own launcher and application management tools. All that does is slow up development, because after the plain OS is released, then Moto/Samsung/HTC/Sony have to build their own UI layer.
BTW, my new simple little fave app is Smart Clipboard. You can save small snippets (with a short name) and it runs in the notification area. So then when you need something like an email address, you pull it down, tap and then paste it in. Super helpful for those things (like email) that you're constantly typing and retyping (my two main emails are kind of long and have nurabers too, i.e., PITA).
