I didn't expect I would spend 2 hours with unhelpful acer customer setvice on the first day I get it…… About 10 keys on the keyboard doesn't work, so I can't even enter the wifi password without vitual ketboard. I really doubt the quality control of Acer as it seems to be a factory defect. I spend 2 hour with the ineffecient acer support team, and tried everything including reset, reinstall, update and recovery. The problem still there. Decided to return it. I bought it for an urgent use, and I really hope I can get something that can be used immediately. Consider this before you purchase it as it may not work and waste your time to troubleshoot/return/exchange it.
