Actually....
I found it quite useful. The new HP machine I bought about this time last year refused, Blankly, to run Vista with any sound as Vista drivers were not available for the chipset fitted. Since I hated the machine anyway I simply took it back, and pointed out the fact that it wasn't capable of running Vista. After a brief game of silly buggers with the salesman I walked out with a refund.
Points for cheek go to the salesman for first trying to tell me that, so long as a desktop appeared and the OS booted, it was Vista-Capable. Then he tried to tell me that sound wasn't an important part of this particular modern multi-media operating system. Then that I had to speak to HP, as they put the sticker there. Then that I had to wait for the sound chipset makers to release Vista drivers. Finally he told me I *needed* to buy a USB sound card for sixty quid (one that, upon investigation, it transpired wasn't Vista-compatible, either)
My answers to this were "Don't be silly", then "why would I buy a PC with a sound card and DVD drive and software if I didn't want SOUND??", "Law of strict liabilities", "Do be serious", "Will you get out of the f*cking GARDEN??".
