Dell has just released the new Studio One 19 All-In-One Desktop and our first impression is that its a nice improvement on their earlier model.  If you're not interested in a Mac, but like the iMac form factor, you'll want to check this out.  From a design perspective, this is probably the best looking hardware dell has ever produced.  The computers come with a 2.5GHz Dual Core Processor (with the higher end models featuring a Core 2 Quad processor), a 19" Screen and up to 500GB Hard Drive.

Dell is offering discounts on the higher-end models, which all cost under $1,000 after the discount.  You can get the base model for as low as $699.
