T Mobile Smart Phone Recommendations

[notasherpa]

I am a T-Mobile user and am looking to move up to a Smart Phone. I currently have the Blackberry Pearl and want something with a data plan. There don't seem to be too many offerings at T-Mobile, so I am looking between the Samsung Vibrant and the TMobile MyTouch Slide. I like the Samsung better, but I'm thinking I'd like the qwerty keyboard as I currently find typing on my
Ipod Touch to be challenging.

Does anyone have experience w/ the Vibrant - or any knowledge when the next T-Mobile phone will be coming out - I think it is called the TMobile G2.

Thanks for your help.
