I'm currently in the process of developing for the NIOS embedded processor platform. The software development suite runs much better on XP (which I have) but I don't want to think that I cut off 20GB of my HD just for that. I want to justify that by installing Windows 7 and using XP mode for my development needs. Is this smart? For previous users of XP mode, is it fast enough? I'm not running any games, just Xcode-like stuff and maybe a simulator (probably not). Is XP mode suitable for me? What are your suggestions, use XP or Win 7?
