I have a Droid 2, I like it more than my computer.
Angry Birds is awesome.
Your battery won't last much longer than a day. Bluetooth and other battery guzzling options are off by default, not much you can do there. And Skype is a default app.
Also, learn to use Swype. Long hold > Input method > Swype > Long hold on the bottom right button for a tutorial. Its fast, fun and neat.
Download Pandora if you like music, or TinyShark, but Pandora is cooler.
Ummm, get Lookout if you do a lot of websurfing too.
...and yeah.
And yes, Android supports Flash 10. <3
Get Zedge if you want some cool backgrounds and ringtones for free, too.
