Dell's Studio One 19 replaces the XPS One. In terms of upgrades, the new version adds a touch screen and Dell's own touch interface. While it doesn't have an Atom processor, the Studio One does come with a lower price tag. It's available now in Japan, and the U.S. later this year for $699 to start.
The WindTop from MSI is almost identical in features to the EeeTop from Asus. The WindTop also boasts a touch screen, but it has slightly more real estate at 18.5 inches. Also inside: an Atom processor, Windows XP, 1GB of RAM, a 160GB hard drive, 802.11b/g/n Wi-Fi.
