Sure, but actually they don't buy new machines any longer, or very few. They recycle within the company... Recent machines were bought with 2GB, but older ones only came with 1GB, or even less.
Also, I don't use heavy applications, but a lot of "medium" ones. And when our admins decide(at least once a day) it's time for a windows update or mcafee update, I can go get a coffee without hesitation...
Regarding eBoostr, I probably made the window capture just at the wrong moment, since I feel it improves a bit the overall usage of my current machine, especially by reducing virtual memory access and HDD trashing. But I may be wrong on that.
