we used dells...
most of the computers the fauclity used in their labs (which wasn't much, i went to a smaller college and we didn't use computers for lab work) were dells. in fact, most of the schools computers were dells (thats another story). but to see that computers are much a fact in most bigger time labs amazes me at how intergrated at techology we have become in science, and how more than ever we need people that are proficent in windows and macs.
it was a great tour, got me to peek in a first class lab, instead of the mostly cramped and (sorry) second rate ones we had.
