Been playing with my new transformer and have a couple of questions that i have not found any answers for..help please: -how do i switch between open/running apps? -how do i turn off the "searching for gps" process at the bottom of the screen? -i am using the default e-mail app. How do i log out? -typing is very laggy, is there any way to reduce the lag. Occurrs with hardly any other apps open. Thanks!
