Use the Acer Aspire now since August and am completely satisfied. Everything works well and quickly. Also, the Windows 8.1 is no problem, because I go on the Windows icon on my normal desktop and then everything can be used almost like the familiar Windows 7. Am completely satisfied and happy that I have motivated here to this purchase, the positive reviews. So thanks to everyone who took the time to share their experiences here. And the little icing on the cake for good technology, this color is really great :)!
