Task Kill and widgets
Noooooooooooo! Don't mention Task Killers!
This is something that gets lots of droidheads (rightly or wrongly) quite hot under the collar.
It does seem the droid OS monitors itself very well and that (apart from badly written apps or widgets), inteference by the user in killing unused apps doesn't help the phone work better, or increase its battery life.
Anyway, for my list of must have widgets:
(#) MixZing (with music player) - Controls music from homescreen
(#) Gemini Calendar - nice calendar app
(#) GTasks - Good google task integration
(#) Photo album - choose on your pix, and put it in 2x2 picture on the homescreen. 'Click' it, and it takes you to your photo album. Handy!
(#) Just adding a +1 for Extended Controls - easy switch on and off WiFi, 3G, GPS etc which are easy ways to extend batt life. It Even has a numeric batt life icon, a shortcut to use the phone as a torch, and a shortcut to switch off the autokeylock (useful when the phone is safely sat on your desk)
The final thing I like about it is that you can choose much space to squeeze the icons into - there's lots of flexibility...
