Which camera?

[Mandy]

My oldest daughter's birthday is coming up and she's wanting her own P&S camera.
She had a Sanyo (before the dog ate it ) or something equally as crummy from Walmart but she's really started taking an interest in photography and so I thought I'd get her something a little more advanced than the Sanyo, something portable and something somewhat cheap. I'm thinking of upgrading my SLR next year so she'd inherit my Rebel 300D and I want to prepare her and let her get some practice in before that.

So I'm deciding on three cameras.
The Sony Cybershot, the Nikon Coolpix and the Canon Powershot. All 3 are 10mp and cost around the same amt.
Does anyone have any thoughts or experience with any of these?
I'd like to hear what people think.
Thanks!
