Re: Will any of you upgrade to Windows 8 when it's out next year?
Betas don't, no -- they're not released products. There's usually some restriction on getting them (like an MSDN subscription or being a member of the BizSpark program, etc.) and there may be a cost to that part of it. Your license to use the beta (or release candidate, etc.) evaporates the minute that the product is released in your market.
