For a price no, but for free, yes
I converted my mom to a BB last week after almost 10 years of using a dumbphone and she's loving it, she's a BBM'ing, SMS'ing, Emailing Machine.
Originally I had planned to swap my 9000 for her 9700 once I unlocked it, but after playing with her 9700, I don't know if I want it anymore.
It's like typing on my old 8310 again. The size of the 9000 isn't an issue for me since it fits in all my pockets and I love typing on my 9000.
Although if she does want to swap for free, I think I'll take it just to have a new toy, and use my HUP on the next flagship BB.. maybe a Storm 3 (if the phone ever goes to Rogers) or a Bold 3
