Trying to decide whether to exchange my Acer W510 for the ThinkPad Tablet 2. Two things holding me back unless someone can chip in and give me some real world information. 1. How fast does the ThinkPad Tablet 2 charge with the provided A/C charger? I love how quickly the Acer W510 charges so would like to know if the ThinkPad Tablet 2 is the same over the mini USB charging. 2. What real battery life are most getting with the ThinkPad Tablet 2? I'm getting easy 10 hours on my current Acer W510 now. I read one poster saying that the ThinkPad Tablet 2 was a bit slower than his Acer W510, anyone else can verify if you notice a bit of lag compared to other Atom processors? I don't mind if it is a few blinks.
