All our current computers are over 4 years old. They still work fine now, but they might need upgrading once we start using AC full time and find out if they're too slow or not. At that point, we might get a real server OS and use the Vostro to replace one of the workstations.
Most of my computers are 4 years old, Pentium 4 (2.4-3.0) with 1.2-2 G of memory. All are Win XP. They have worked fine and there should be no reason to replace them for version 5.
HOWEVER, I have upgraded one office to V6. It seems much more processor hungry. I had 2 dual core 1.6 with 2 Gig XP machines that I had to replace front desk and another, I will need to replace the others, prescriptions especially are slow. I may wait and see if I get money from the feds. If so, then new vostro's are in the works. I priced up one at only about $570 but I will need 10 machines. I have run peer to peer. I may upgrade to a server (actually 2) if I have fed money. If not... well more refurb dual cores may be in the works (139 + memory).
Maybe a future release of V6 will be less of a processor hog.
