For all of you post about what does not work with Ubuntu, read the Jim Louderback column in the 8-15-2007 issue of PC Magazine.
He says "Maybe it was something in the water? I've been a big proponent of the new OS [VISTA] over the past few months, even going so far as loading it onto most of my computers and spending hours tweaking and optimizing it. So why, nine months after launch, am I so frustrated? The litany of what doesn't work and what still frustrates me stretches on endlessly...Take sleep mode, for example. Vista promised a new low-power sleep mode that would save energy yet enable nearly instantaneous resume. Poppycock...have to cold-start it to bring it back. This after replacing virtually every driver inside. It's gotten so bad that I've actually nicknamed it Chip Van Winkle...I could go on and on about the lack of drivers, the bizarre wake-up rituals, the strange and nonreproducible system quirks, and more. But I won't bore you with the details. The upshot is that even after nine months, Vista just ain't cutting it. I definitely gave Microsoft too much of a free pass on this operating system: I expected it to get the kinks worked out more quickly. Boy, was I fooled! If Microsoft can't get Vista working, I might just do the unthinkable: I might move to Linux."

So let's not think that Windows is perfect and Ubuntu is not! All OS's need work.
