I try to keep a few years behind the OS upgrading curve. I think I used 98 SE until about 2003/4, and I've used XP since then. My brother has been running Vista for the last year, but only because he has two 8800's and needs Vista to run them dually.

At first glance, Vista looks nice. Lots of animation, lots of protection and lots of automation. Until you actually try to do something, and realise that Microsoft has moved everything for really no good reason, making the whole experience feel very counter-intuitive.

A few things I've found that rubbed me the wrong way (yes, mostly minor)
- Putting the 'make shortcut' button in the 'Send To' grouping.
- Vista doesn't like to play nice with XP machines on a home network. We can access it, but it can't access us. No matter what we try. All our other XP machines have no problem reading each other.
- The lack of a functional root directory in the Windows Explorer. It feels like they went for aethestic value and lost functionality.

I'm sure there is more but that's all I can remember at a moments notice. I'll be waiting another year or more before upgrading to Vista, if at all. And other than an iPod, I've never had an interest in any Apple products.
