When the Dell XPS One A2010 comes to market, it will join the Gateway One, the Sony VAIO LT19U, and the HP TouchSmart as Windows-based competition to the Apple iMac.
The reports indicate that Dell will have options for a Blu-ray burner, 802.11n wireless, Bluetooth, and a TV tuner, making it more in-line with the higher-end VAIO than with the more mainstream Gateway One. With those specs in mind, we'd guess pricing will be similar to the new XPS 420 desktop--between $1,500 and $2,500, depending on the options--although possibly higher due to the added cost of heat management and space savings in a confined chassis.
As we said, assuming Dell releases this system with the specs as reported, every major desktop vendor will offer a reasonably priced all-in-one. If you're not shopping for a budget PC, if you're not a gamer, and if you're not a video editor, these systems seem to offer everything you'd want in a modern computer. We have to ask, then, what again is the purpose of a traditional midrange desktop?
