Hmm, that sounds like a reversion to the 1960/70s-era model of computing,
Well you need to remember that that's the only form of computing the Bill Gates understands.The advantage of thin clients are that they don't need much power (since their programs are running on the blade server) and thus aren't as attractive for thieves. The blade server of course can be locked inside a secure server room and bolted into a 19"rack (along with the SAN giving automatic redundancy and backup for data), which in turn is bolted to the floor and wall, making thievery of corporate property a big nuisance. The school I used to work for (now a client) has only had one break-in since they switched to thin clients 5 years ago. They used to have one every other month.
