Looks like a pretty good setup. I wouldn't get too excited about Bluetooth or Firewire. Since USB2 came out, and with the new version soon due to appear which surpasses Firewire in bus speed, both are slowly sinking into non-use. But it's okay to have them on your unit, just that I wouldn't pay any extra for them.
The only thing that I see for definite improvement is your pre-installed Operating System (OS) on a restore disk. This is a "land mine" that one day will cause you heartache. With a 320 GB harddrive, you will eventually have a lot of data and programs loaded. One day a virus, adware, malware, equipment failure - you name it - will corrupt your OS. With a restore disk you will be up a creek without a paddle. If you restore, you lose everything on your drive. I see it all the time here on the hardware forum, with folks that face the hard reality of losing all their setup proggies, data, everything. Zip. Not a nice experience.
Try to negotiate a deal with this outfit, where they will substitute a standalone XP disk (with SP2!) that you can purchase. Even if you pay a little more, believe me it is worth it. Now if you ever get corrupted OS files, you can do a repair-restore from the XP disk in the CDrom and you are on your way again.
Another thing you migh think about that isn't all that important, is having a second burner. IF you do a lot of disk-to-disk copying, Nero is great at doing fast-copy disk to disk copy. Just a thought.
Other than that, seems to be a pretty solid unit. Wish you the best!!
