I am packing up my brand new Dell Dimension 9200 and sending it back to Dell because Vista was SO UNSTABLE! It locked up 3-4 times per day. Dell's diagnosis? I was installing incompatible programs - like ITunes, McAfee and Palm Treo software - all the programs I use daily. Their "fix" was to reinstall the original image and not use any of the 3rd party programs until their "Vista Compatible" versions were ready So they'll take it back and I'll wait... (Like you should!)
