The Lenovo ThinkCentre M90n Nano is an adequate mini Desktop PC that is powerful enough for general use, office work, and media streaming. However, it's not much better than similarly-specced Ultrabooks. Given the high price point (~US $1080) and the additional cost of a display, a mid-range Ultrabook may be a better buy.

I am somehow jealous/upset that laptops don't have as many USB ports as this excellent nano PC. Despite being far bigger and having space to accommodate them! Why?
