I'm not loyal to any device so my opinions are completely objective. I initially stayed away from Android because it didn't have voice dial over bluetooth, that has changed.
Since Windows Mobile isn't back to full strength yet I decided to try Droid because my Omnia and I weren't getting along any more.
I have the Droid 2. It is not as functional out of the box as my Windows Mobile Omnia was.
I can't sync it with outlook calendar, notes, and tasks.
The default email app doesn't delete emails from the server using pop3.
The voice command app doesn't read my incoming text messages.
The preinstalled quick office doesn't edit documents (couldn't delete rows). Had to buy documents to go.
The default sms app doesn't turn the screen on. (installed handcent sms free)
The live wallpaper is cool (not useful though). The free voice turn-by-turn navigation is great.
The speech to text is great.
Moving between screens is very smooth.
Battery life, I don't understand why people complain. It's a smartphone, it can do tons of tasks at once, if you use any smartphone to its potential the battery life will suck, just charge it more frequently, problem solved.
There are a lot of apps, useful, practical, just for fun, non functional.
So far handcent sms is fantastic. It allows you to set sounds and visual notifications per contact.
Vcast song ID, just like shazam.
Dolphin HD browser allows you to see full websites instead of just the mobile versions.
Youtube ripper allows you to save youtube videos.
If Google would allow for syncing with outlook (not exchange) and they enhanced the email app, I would be very happy with the Droid 2. Right now I have to settle for satisfied.
