First off, the new internal wireless card showed up for my VAIO yesterday, and that went in nice and easy. Funny how reassembly is always about 10x easier than disassembly. Supposedly this machine can only handle 1GB of RAM, but I swiped 2GB from work (that I bought and never expensed) out of a machine I've been testing Vista on, and what do you know, the 2GB works fine in the VAIO. But Vista needs lots of RAM. Should I keep the 2GB in my VAIO and put the 1GB into the work machine, or should I put the 2GB back in the machine that needs it more? Also, when XP first came out there was a lot of wailing and gnashing of teeth about the Prefetch function, and apparently lots of people disabled it before they realized it really is useful after all. But, my VAIO has an SSD in it, and disabling the Prefetch continues to be recommended for SSDs. Anybody know if there really is a good reason to disable the Prefetch on an SSD? Is it designed to make up for a deficiency in rotating disks, or would it be useful when every bit of data is equally accessible at all times?
