I think they really were caught by surprise by how many people wanted it.
Guess Vista really is that bad for some people.
Anyway, not a single issue (other than Chrome not working) so far, my PC has been unstable recently on Vista x64 but hasn't gone off once yet.
I wanted it badly and Vista is great for me. I think it may be people on XP who wanted to skip Vista, or other things. One issue for me is I have Vista X32, and I kind of wanted to try x64 (which I have on my laptop) on my desktop, that makes it riskier I suppose though since I cannot run x64 in x32 VM or whatever. I will probably just give it a go though as my primary in a week or so and leave it until August baring unforeseen total catastrophic issues.
I think I will just purchase a new internal drive and install onto that leaving my other drives disconnected to see how it plays out.
