The desktop, which offered an AMD Athlon II X4 2.2 GHz processor, up to 4GB RAM, and ATI Radeon HD 5450 discrete graphics, was described by PCMag as “a cut above more basic all-in-one desktops”. The pros were listed as the compact size, the discrete graphics, multi-touch 1080p HD screen, HDTV tuner, and wall mount. The cons were indicated to be the remote which required an IR dongle, the lack of a Blu-ray reader/writer, the lack  of HDTV input besides the TV tuner, and the Microsoft Office 2007 installation, which was a trial only.
