Gee, I wonder why no one responded to that... Especially at xda.
I know, right!
unclekeg - A couple things:
I'm a Palm/webOS convert as well, and I hear you on your comments about the Android community. WebOS community was much much smaller, and centrally located, and therefore tighter knit.
Android community is far larger, and more spread out. I think you'll find you may have to do a bit more leg work to get the the place that gives you the answer you need. But, this is a great place, no doubt about it.
XDA folks seem to be on another level. Understandable that you may not get a response there. (I kinda equate them similar lines as the webOS Internals guys - far beyond most of us.

)
On your question: try K9 email. I can't comment personally as I don't have it installed, but it's massively popular. Nearly everything I could do on my Pre I can do on my GS2, and way faster, on a much much prettier screen.
Milominderbinder's sticky's should be must-read's for anyone new. I'm pretty sure he even has a dedicated coming-from-weOS section.
Lastly, give the conversion some time. I think you'll find the folks here are very helpful. I know they've helped me a bunch already.
Hope this helps.
