I don't really want to install Windows on my Mac but one of the companies I do work for I need to be able to access their intranet remotely and their IT dept will only let me install the VPN /Terminal Server in a Windows environment (with up-to-date antivirus software ). So, the Mac I will install it in is 12 months old Intel Alu iMac with 2 gig ram, the HD is 360GB with only about 1/3 used. I have not intention of installing much in the way of software apart from a windows OS and the VPN software, and I suppose antiviral as well . How big partition will windows need? Oh, I havn't upgraded from Leopard to Snow, but will it it really makes a difference. Given I've been writing across my HD for a year will I need to defragment the HD prior? Shall I install XP/vista/windows 7. (remembering the purpose is only to use VPN). (the company won't pay for the OS as they don't like Macs to start with.) Thanks.
