HP G71-449wm Laptop PC with Intel Pentium Processor

I recently bought this but I am not loving it. Although the 4 Gb ram, which is more then enough you cant upgrade it in future. Also the touch pad and the silver body gets hot which is uncomfortable. And I also think the Display/ Graphics is not for gaming either. I compared World of warcraft in my Desktop and laptop, The colors seems blurry, Purple looks blue in the G71-449wm laptop. So I am thinking of returning it.
