I installed Vista again on my desktop and I had to reinstall the operating sytem 3 times in a row. It just wouldn't operate correctly and the programs kept crashing. I had xp on the machine after my computer came with vista and rarely had problems with it but I don't want to mess with xp anymore...I just want something new. I now have Linux Ubuntu on my machine. I am thinking about getting a quad core desktop with 4 gb of ram and Vista Home Premium for around $500. Should I do it or wait? My current machine has 1.5gb of ram and a 2.2 ghz one crap processor. I paid $220 for the computer. I heard that Windows 7 is coming out by the end of the year as well...I just don't know what to do right now.
