I actually didn't tell enough. I have had 2 Asus, 1 Dell, 3 Lenovo, 1 HP, 1 Chromebook, 1 MBPr 2013 late. In the span of 5 years 2008-2013. I only stick need my Apple now.

I purchased and sold 4 of those the Asuses, Dell, and HP. The Lenovos were purchased by my Prof. I complained and she gave them to the incoming students and I got a new one.
