Fast, great, I've had several months, although holding a charge, updates to Android are PrtSc (in 4.2.1) I recommend the following free KingsoftOffice very close to Office 2010/2013 and records the corresponding format. I purchased the Asus bluetooth keyboard, a feast, do not hesitate to work to buy the microUSB connector / USB (for external mouse or dd) and fitting microHDMI / hdmi female to project on TV. ASUS so glad that I just bought transform the T100 32MB for when I am forced to be Microsoft.
