Conclusion: You can find better choices, in terms of multi-touch support and a more flexible display, for those who spend most of their day using or developing touch applications. But for basic office use where touch is simply an added bonus, you'll come to enjoy the plain but highly functional ThinkCentre...
Pros: Competitive performance, Quiet operation, Stellar Webcam performance, Bundled keyboard and mouse are pleasant surprises, Three-year warranty
Cons: Two-point touch support insufficient for Windows 8, Display cannot be laid completely flat, Drab design
Conclusion: The Lenovo ThinkCentre M92z is a very good Windows 7 all-in-one business desktop with a responsive two-point touch screen and quad-core power. Unfortunately, Windows 8 is right around the corner with new requirements that the system doesn't quite match.
Pros: DisplayPort-in and DisplayPort-out. USB 3.0 ports on side. Internal power supply. Shutter on webcam. Good physical buttons on front panel. Function keys default to usable functions. Comfortable keyboard. 8GB of memory.
Cons: Only two-point touch. Raised bezel. Single-band Wi-Fi.
