never happy people, this is a tablet with WINDOWS in it, it's windows, not android or IOS, this is a pc to work...... you can't have the wife drunk and the bottle of wine full as we say in Europe. If we want the device with longest battery chose an useless ipad or galaxy tab, Sp3 is like it is, takes or leave, we use, or I use, to work, and it's a miracle what I have today. I don't take care of battery, can last 1, 2, 3 hours or 10. I had a lot of laptop in my life and when they were good for job and performing, battery usually was lasting few, perhaps I used them as main desktop I rarely used just with battery, but even that time I was not goind to look for the laptop with battery lasting more, what is important is the product, productivity, I need windows to work and make $$$$, I don't care of battery, I can spend sometime more to recharge it or use a wall cable and go on.......... I love Surface Pro 3, this is the future!!!!!! Be happy to have a device that work perfectly, I think a lot of people just like to test products because knows that can return it to the shop! We bought here in Europe importing from America, no warranty, no returns, takes or leave and I'm happy!
