At the Windows User Group last night, one of the MS Ireland guys had an Acer “Atom” net book with 1GB RAM. It was running Windows 7 pretty well. I’d probably still recommend 2GB RAM but it did appear pretty good.
Dave Northey from MS Ireland showed BranchCache working with a pre-beta build. His normal demo laptop died earlier that day and despite running on sub standard h/w he go the point across. It isn’t actually block based like I had thought. It is file based. It will still improve things drastically but leaves a window open for alternative branch office solutions.
