Well it won't be out until late summer probably, most likely October is my guess kind of like when XP came out.
I will probably get a hookup on it around November 06 from Intel, since every year Intel allows retail employees to buy a processor, motherboard, the latest copy of Windows, and some other software for around $215 TOTAL. This year it was a Pentium D 820 with the mobo, Win XP Pro, and Photoshop and Premiere elements for $215. Next year I imagine they'll bundle Vista with whatever package they come up with.
I will also get the publically available beta that comes out I think in a month or two, and release candidates. Those last for 120 days, which should be enough for me to get a good feel for them. As a Geek Squad agent my priority is to get my hands on Vista early so I can learn how to troubleshoot it and fix it and of course use it so I can use that knowledge for work.
I don't feel like upgrading for the sake of upgrading. I used to be like that, always wanting to get the latest stuff, and sort of still am but I don't get to spend that much time on the computer anymore outside of work.
