small business that is. He owns a small car stereo shop. He is using old PC's and would really like Apple's in the store. He currently uses three computers, two in the front for the sale staff and one in his office (all computers are networked, the office computer is used to back up all company data from the sales computers). They use Quickbooks as there main app, internet for research, they would need an app for appointment scheduling, and a way to connect a fax machine to the office computer to recieve all incoming faxes. Are Apple's a viable choice for him? I suggested the $999 iMac's. I figured that would be good enough since the current computers are a 1.4GHZ AMD Athlon w/256mb ram and 20GB HD, 933MHZ PIII w/512mb ram and 40GB HD and the office PC is a P4 2.4GHZ w/512mb ram and two 80GB HD's (one for backup). What do you guys think?
