Thank you both for your responses!
I think I am leaning more towards the 7290, as I plan on keeping a separate cell phone for at least the next year/year and a half. I will mostly be using my BB for email.
CyberJ...I did see the refurb ones at Cingular. I'm a little bit reluctant to buy a refurb (maybe I'm crazy!). But...it would be a huge savings, so I won't rule it out just yet.
I look foward to any other opinions...
