I bought a Microsoft surface pro 2 for over $1300 maybe two years ago. Six months ago I cracked the screen on it and paid $350 for a replacement unit. The battery on the replacement unit is now defective and needs replacement. Cost? $480.I was unable to get my issue resolved thru tech support. When I finally got a hold of someone at Microsoft corporate office they were wonderful. Very attentive and follow up was great. I am glad some corporations still take the time to listen to consumers. Problem solved and I am satisfied with the resolution
