Wheeee! I just installed Vista today. It took Hours. When I got the upgrade package, the instructions said to allow four hours. Bullhoggely. They meant four hours just for the discs to run, not four hours all together. That four hour time solution does not count time spent going to Microsoft for updates, both before and after the install, nor does it count the time spent at HP looking for new drivers and downloads, nor does it count the fact that if you're using Norton Internet Protection you must go there and download the program, since you had to uninstall it before the upgrade, not to mention that you have to run a system scan beforehand. When I said "discs" loading, I got my upgrade through Moduslink. Because Microsoft was late in delivering Vista, there were a lot of computers sold before Christmas without the new OS. To make up for it, Microsoft agreed to the updates, and the manufacturers had to handle the distribution of same. Moduslink was hired by HP to handle their upgrades. What a nightmare. I had to enter a certificate of authenticity number from the unit on the Moduslink site. I lost my connection right in the middle of it, and the COA wouldn't work. I kept getting the message that it was not valid. After a couple of phone calls to both Microsoft and HP, I finally sent an e-mail to customer service at Moduslink, and they got me validated again. I then went back through the order process, which took about eight weeks. I just found out yesterday that I was not the only customer with validation problems. It turns out that a lot of people dealing with Moduslink had the same problem, and a lot of them had problems with delivery. I guess I missed out on that one.

But you know what? This thing's prettty cool so far. I guess the working word at first is "smooth." It seems to be smooth. I haven't gotten into anything like Movie Maker, or even Media Center yet. The Aero graphics are slick. Or smooth. I couldn't wait to learn how to tile the windows. So far, no hardware problems, no compatibility probems with software, although HP pretty much removed all of that with their first upgrade disc. So I'm going to play now.
