@Boris H. calm down... eh.... eh.....
"Now that you are such a big Fan(some would say shill) of Vista please do tell me what is the new feature in it you did not have in XP and can not live without now."
Is that a flame? have I been flamed? gosh!
"The pretty interface had to go with first 20 minutes, and the old windows look was there after 25 (as soon as i figured out where they hid the interface this time)."
Ahhh.... you must be the luddite Iwas talking about, probably the same kind of person who changed the XP look and feel to look like NT calling it the "Windows Duplo Edition"
I like Aero, I liked it when it was running on Linux before Microsoft mimiced it (and when it didn't require a 256Mb graphics card).
Anyway, back to you(r) (f)lame.... what does Vista have that I can't live without? ummmm.... nothing? OK, there's better user control, bitlocker (but not in business edition.... durrrrr), IP6, better crypto, readyboost looks promising and the media centre is much better (media handling generally is better, not DRM 'tho), but will I die if I don't have these? hopefully nobodys life will ever depend on a Redmond product.
I don't *love* Vista, but it's not a big deal (for me), I've run it on fully certified kit (lovely) and uncertified kit (not so good), I run XP on my laptop (lightweight and quick), I run 2008, 2003, Solaris, Aix, Linux and nothing gives me any serious gripes (I'd like to see 2008 a little more stable) Vista isn't a big leap on from XP, only a few better things (maybe a quantum to use the term correctly), and as I said the inability to use XP drivers was a really bad thing, it's bloaty, but it does more in the background (even if it's pointless), lets face it, Microsoft could have added the extra features into XP SP3 and given it free, but that wouldn't have been good business sense.
If you're buying brand new kit for the home, go Vista.
Don't upgrade to Vista from XP.
For business I'd use XP Pro and always use disk encryption.
Enterprise, use 2003 for Exchange/BDC/PDC,Workgroups,Sharepoint etc. (Solaris or virtulised Linux for high end DB servers)
There you go... sorted :-)
