Windows Vista - Compatibility is an Issue

I bought Windows Vista expecting an upgrade to my Windows Xp experience.The positive is that the graphical interface is much improved and I find it easier to access programs where I would have trouble finding on Windows XP.My main gripe is about the compatibility that Windows Vista currently offers.Many programs that I have attempted to run on Vista simply fail to work.Now, this primarily has to do with games and software of the same genre, but I am an avid gamer and I just get angry when a game I buy isn't windows vista compatible. All of the necessary programs work, of course, but the expanded array of software available is largely incompatible.I would think twice before switching to Vista, and I would recommend any consumer to wait at least 6 months before purchasing this product.
