In my research I looked at 1080p systems from Sharp (LCD Flat panel), Sony SXRD (non-DLP rear projection) and DLP sets from Mitsubishi, Toshiba and Samsung.
The IdeaCentre A600 all-in-one offers several connectivity options including high-speed WiFi, a 6-in-1 media card reader, side-mounted USB and FireWire ports with additional USB ports on the rear of the panel.
