Summary: Excellent replacement computer for those dealing with end of support for Windows XP. Fast and easy setup. Startup OS is Win 7 Pro 64-bit so you don't have to deal with Win 8 if you don't want to. Plenty of USB ports (10), especially USB 3 ports (6). Small footprint. Excellent choice for those who want the Win 7 OS and need extra firepower such as for heavy duty number crunching.
Summary: This is a great compact and powerful computer that does the job for basic word processing and photo editing (which is what I use it for) so can't comment on stuff like gaming and/or video editing, etc. I love that it is very quiet & takes up a very small footprint. If you don't need the optical drive it can be removed for an even smaller form factor.
