he's on vacation this week, but I'm sure he'll be absolutely happy to respond when he's back :)

if you really need to know soon, he's mentioned a few in the staff channel, so I can go through the logs if you find + bug me outside of work hours... :p

does your mom live in qz's area?
If she's looking for a desktop, you could ask qz to build her one, if you provide the $$$ get the parts shipped to his place and maybe some RAM for his trouble :p
I would certainly do that for most folks -- computers are cheap to build yourself, and if you're not savvy with them, salesmen may take advantage of you. I hate seeing people get taken advantage of, since building computers is cheap. Laptops not so much, but if she wants a desktop (which is what I gathered from your story) those are very cheap to build yourself if you don't want a gaming or editing rig or something.

Or alternatively, you can order something online for her and get it shipped to her house. I've done both for my parents (who aren't super computer savvy) but I've found building it myself is better value, if they're looking for a desktop. I'm the only really techy guy in my family right now (even extended family) at least until my cousin goes to school next year, so I know your position well :p
