Installing Vista

I finally got around to installing the freebee Vista Ultimate I got at Mix last night. I started to sweat a bit when the installation got to the 'expanding files' bit and stuck at 27% for about 15 minuets. After googling, it looked like a few people's Vista installations had failed at the same point and I was just about roll everything back when my wife distracted me. Five minutes later I went back to the installation and it had started moving again. I wonder if the people who were posting about the installation freezing had waited long enough? My Dell dimension 8400 only gets a score of 2.4, mainly because of the low end video card, so I don't get all the wizzy aero graphics; maybe it's time I invested in some new hardware :)
