Summary: It has served me well. Purchased in 2009 or so. Not crazy about the facial recognition sign-in, so I disabled it. The cover camera is low-mid quality, but suitable for most uses. It has now become a slug, so I will be installing an SSD drive and Windows 10.
Summary: I bought this laptop in 2009 and boy has it stood the test of time. I did have to change the battery on this device a couple years ago as it was no longer holding the charge. i opted for a 'non-brand-name' version and have no complaints .
Summary: Surprised that the reviews are not distinguishing between the buying experience as to new and used machines. I am writing this in 2014 and if you are reading this, you are considering buying a used G550.
Summary: One substantial deficiency of this laptop is the inability to adjust the 'sensitivity' of the touchpad. As delivered, the pointer was dificult to control with any precision through the touchpad. The location and movement is erratic.
