**disclaimer** I'm just teasing here, not trying to troll or rile anyone up. I'm an ex-bb user and I had the same initial longings for all things berry. Don't worry, the pain will pass and will be replaced by sweet Android bliss.
Lots to miss about a Blackberry?? Sure... battery pulls, random reboots, leaking memory, hourglasses spinning endlessly, horrible apps, lousy GPS, oh... the good old days with bb (*sniff*)
You miss notifications? HUH? stupid Android.... no notifications. Seriously... I'm NOT understanding you here. Do you mean profiles?
You miss the calendar? HUH? that was like a 1980's calendar that was only ONE calendar. The Android can link as many calendars as you want to as many email accounts as you want, on screen widgets with skins and all sorts of options, and free calendar apps - The calendar on thsis device is crazily better than BB's lousy, clunky, ugly one.
Battery life... well, you got me there. However, I would expect the battery to die on my Droid 10 times faster - it does 10 times more.
