I have not had this computer for a long time, but would have to lower the price because of a malfunction: when typing the prompt suddenly jumps by itself to somewhere else, but other than that no problems, I have managed to clean it from malware with Malwarebytes and Microsoft Security Essentials found one virus by itself which it removed. 1.6 GB RAM available but expandable to 7.6 GB available. A year old. AMD CPU. Not discrete video card. Decent battery, 2½ hours. Windows 7 64-bit. Microsoft Office 2010 Starter. Built-in magnesium frame. I have no bag for it.
I have the opportunity to change to a laptop with large monitor, 18.4" 1680*945 pixels. It costs ~$45 less than what I paid for the 15.6" laptop. 4 GB RAM.

A review on the internet says that this model has problems with overheating. I guess it also has a built-in magnesium frame. It doesn't come with any bag.

Total number of books with licenses: 621. My Gk skills are at the very beginners level. I'm going to study classical Gk in uni in 2014, after that a bit of theology, and then Biblical Gk, ...
Are large computer rucksacks very expensive?
If I don't buy it, my option is to put more RAM in my existing computer. I have no clue what that would cost including the work.
