I like Vista too, my old Medion laptop had Vista Home Basic, but I got a lot out of it; and yes Vista is a bit slow and is buggy with a strict UAC but I enjoyed it and each Windows OS had its flaws but there are fixes for them.
I still think its better than a MAC (they confuse the shit out of me, Vista doesn't). But I am going to get the upgrade disk for windows 7 once my computer is fixed. They need to terminate Vista completely
While the stats on my pc would reflect what you've said I still find that everything works faster than on my old XP machine. I've still got 2-3GB Ram to play with (out of 4GB total) and you always lose a percentage of your hard drive, it depends how big it is as to how many GB's therefore, I think I've lost nearly 30GB on my 500GB drive.
It is a great system to work on, everything seems to flow well, and I've not even had to reinstall since I first got my machine a couple of years ago
I see, well there's your major problem, the RAM isn't really enough to run Vista properly, its the minimum yes, but personally I would always suggest 2GB minimum, its not expensive anymore either, you can pick up 2GB of DDR2 for about £30 now.
It always happens, people believe the hype about bugs. I've been running vista for 9 months now and I've had no bugs and no viruses. Absolutely nothing wrong with vista, it runs perfectly with the right hardware
