Dell... ok not going there as this thread does not need to turn into the Mac vs PC commercial lol
So all of my statement is purely imo
HP, they have a 16t and 18t series out now and I love them - HD display, Blue Ray Player Media Center w/ remote, TV tuner, Fingerprint reader Vista 64 bit (other options) and I snagged it when they had tons of free upgrades and a hunted down a coupon code online for -$350

so I ened up getting a 16t series nearly fully loaded for her at the amazing price of $650 which if I would have been an average Joe and purchased online it would have ran nearly $1,300 that's double for an hour of online investigation and coupon code hunting I can live with that.
All I'm saying is check around no matter what you buy, try coupon codes and you might have to call as some won't work online they have to hunt them down on the phone. I have been seeing some decent systems listed from all manuf's on
www.slickdeals.net check it daily, I do.
Hope that helps you find more for less, personally I could go either way PC or MAC but in PC Brand is argued A LOT but for me again, imo... HP.
