This is my unboxing and first impressions video (part one) of the Lenovo ThinkCentre M90z all-in-one desktop computer. The M90z features a 23 inch, 16:9, 1920 x 1080 touch screen display, 4 GB of RAM, a 500 GB hard drive, a DVD burner, uses the Intel GMA HD GPU, and is powered by an Intel Core i5 650 running at 3.2 Ghz (with turbo boost up to 3.46 Ghz). The i5 CPU has two cores, and supports hyperthreading, so up to four threads of processing can occur. The M90z I'm reviewing came with Windows 7 Professional 32-bit...which, sadly, means the system can only access 2.8 GB of the 4 GB of RAM. It's a huge waste, and I don't know why Lenovo didn't go with a 64-bit OS. You can order it with a 64-bit OS of course. Distributed by Tubemogul.
