I want to put a 16GB SSD in my laptop and use Vista Ultimate x64. Is that enough space? I was planning on following the guide here: http://www.msfn.org/board/Guide-to-VLite-1...ts-t121545.html Also, if it would make a big difference, I could use Business 64 or even a 32bit version. I have a TechNet subscription, so plenty of licenses. And of course I would like a few extra GB since this will be the only drive in the laptop. If I could have 5GB usable after all OS updates and Office 2007 (Word, Excel and PowerPoint), that would be great. Thanks.
