I work for an animal shelter in Upstate New York. We have about 50 machines running XP Pro. They're connected to a Windows network with a domain.
About half of these computers are used for nothing more than using two web-based apps -- one to keep track of our animals, the other to process credit cards. Having a full-blown desktop PC seems like overkill for this purpose.
The PCs are three-to-five years old, and I'd like to come up with a plan to upgrade the hardware.
Our donations are down (not surprising, given the economy), so cost is a big factor. Can people recommend some options? Some sort of thin client, maybe?
