You and me both, man.
I'm all Microsoft, Dell, and Toshiba at home (Dell desktops, Toshiba notebooks). I do dual boot Linux from time to time or use Linux with a bootable CD distro or from VMWare. Used to own a Mac, but not anymore.
The iPhone's specs are truly mind-blowing. I can't wait to get one in about a year and a half (when my contract is up with my current provider)
I love my XPS 600...it's a real screamer. Running NVidia GForce 7900 GS...soon to be dual 7900 GSs. The dual core processing combined with the graphics and the memory and RAID HDDs are all a real screamer for everything I do. From CAD work to Video editing, to lots of music to (dare I say it) gaming...hehehe.
Son has a XPS 400 and we are networked together with three other machines and those teenage boys are our war crying, WOWing and basically learning great small team tactics and comm very well thank you...not to mention keeping them off the street.
Anyhow, I will ultimately own one of these...but probably not on Cingular. Just have to wait and see who else they come out with it on over the next year or two.
