My wife Daly is San Diego County's premiere Mac consultant. She spends all the time she could spend cooking pondering Mac-L and other related lists. If she doesn't know, it's not a question that can be asked. Write her at daly@san.rr.com and she'll help you out.Mac dealers can be neophytes depending on the store -- you might stirke it lucky.
A lil ol IMac does everything your relatives could want at a very reasonable price and does it lickety split, with far fewer confusing ewwow messages than you might get from Windoze variants. Not that they haven't gotten better lately.
