To be honest mate, i have learnt from experience, why change when the one you have works fine.
I remember making the mistake going from Windows 98 to 2000,
Then i went back, and changed to XP, which to be honest i hated, but i do like it now.
I went to Vista (no choice - came on my laptop) - But i dont like it, much MUCH prefer XP, so i'm staying putt.

Theres alot of buzz on the internet making it out to be some super OS. But when I tried the RC it didnt seem much different to Vista.

I'll probably upgrade sooner or later, but I'm quite happy with Vista on my laptop at the moment, I seem to be one of the few who doesn't hate it, lol.

My media centre is still on XP and thats chugging along nicely. Desktop is ubuntu 9.04, but 9.10 is just around the corner. :)

Dan I'd stay put at the mo Vista is getting there so 7 defo won't be anywhere near as good as Vista.

I'm on Vista h-premium at home and xp pro 32bit at the office and have to say that xp all the way mate wait till sp2 for windows 7 is out then i'd say get it. As for putting it on a second hard drive that's good cos you can use it as a beta for all your stuff then when you do fully migrate all is well (sorry for ramblin)

Still using XP Pro, though have had experience of Vista. Didn't actually mind it and also noticed it didn't tax my system as much as I thought it would.

Won't be going to Windows 7 till I build my next PC. Was going to do that last time, but got lazy and bought a Dell I've now had the same machine for 4 years and it's starting to become a bit bogged down at times. Think it could be partially down to the I/O of the original drive I have rather than the processor or memory (Pentium 4 3.2GHz with 1.5Gb of memory). Fancy a great system next, but will wait for the Core I7 to come down in price a little further and SS drives to cheapen also.

As well as that, I need to stop myself from spending money on RGZ. Induction and brakes feel like they "need" doing

Dan, the setup you have now is good and balanced. 64Bit Xp give you the ability to see above 4G Ram and also depending on your graphics card will share more for cash for the motherboard FSB and graphics. If you like to do high end gaming windows 7 is not ready for it as yet.

I am currently running windows 7 enterprise on my notebook with no problems but I must admit that I only running normal Microsoft applications with w7 no vancy stuff. All the applications I use at work is still running on XP and Server 2003 R1 (production automation)

Windows 7 is using kernel technology sort of the same as Linux. This then enable w7 to start faster then XP and Vista and use less resources (Mem, CPU) Open source technology is also been used. Interesting for the future I say.

My suggestion is to hold on for a bit to what you have at the moment till the gaming and applications development towards w7 is done...

Best Regards

Also forgot to mention windows 7 comes without IE as there MS lost the case. So no IE in Europe on windows 7 be warned if you're buying for your dear old mums
