Thank you all for you input!
I really wish that we had a computer store nearby that carried these so I could look at them in person. Unfortunately that isn't a option.
The only problem I have with the G15 is that it's XP only, but I'll be trying to find my disk or at least purchase a new one.
Changing out keysets isn't a problem for me. I talked it over with my BF about the friend's problem with not being gentle. He said that if he was on the computer, my BF would definately ensure that he'd be less rough or ask him to not use the computer.
When I say that he's rough with keyboards, I'm saying that I can hear him hitting keys from across the room while sleeping on the couch. I have a 40% hearing loss. I'm sure this wouldn't bother other people, but to me, it's like hammer on glass. It makes me cringe at the sounds of the keys getting abused.
I'm going to wait at least 2 months (figuring around June) before I make any decisions. I really like both. I'd rather do alot of reading up before I finally buy another keyboard. I don't really need one. I like my current Logitech Internet Navigation. It was my dad's. He gave it up because it was too big for his desk. I've slowly been upgrading and changing my PC since January. So far everything that I've gotten has worked out great for my uses.
