Well, if I had to drop an opinion I would say it comes down to who you are and what you use it for.
Personal, it all comes down to tastes really.
I'd love to play around with an Android.
For business though, nothing beats the Blackberry, and I don't think any company is really trying. When used in conjunction with a BES, it allows you to push e-mail, force security settings (allow no program trusted access to 'X' controls), content filter, etc.
Blackberry is also supposed to be getting Flash 10.1 sometime this year, so I'm quite excited.
