I currently own a Sony Vai GVN SZ430N. I've had ownership over this notebook for about two years now and prior to that it was purchased for retail and cared for for three years. It's almost the year 2011 and going on into its 6th year of usage and Im surprised that it's still capable of running and operating accordingly. Compared to the other computers out now a days, it's obviously out dated but still is quite capaple. The only exceptions I would have to that is that it's not windows 7 friendly. Yes, it can run it but many of its drivers won't function correctly, if at all. Also, the fan is very poor. after a couple of years of usage, the fan becomes weak and need a replacement otherwise it will produce a very loud sound very much like any other old computer. When that happens the computer overheats and begins to run VERY slowly. My suggestion would be to invest in either another computer or fan.
