I bought this for my daughter to use at college.  She used it for one semester with no issues apparent.  One afternoon it just refused to start up ....fully charged...no response.  SO I sent it back under the warranty and after about 3 hours on the phone trying to assure the person that I was legitimate.  They did fix it and return it within 10 days...YAY...I thought.  2 1/2 months later it DIED AGAIN.  No warning just had turned on that morning no problem but that afternoon it would not turn on and I waited...no go for two days now.  RETURNING AGAIN ....SIGH...if company wants business they may want to back up their products with performance.
