11.024...I am an email, platform / charting user.  big improvment from my 5 yr old HPlike:  quick start up (dump edge and bing and it will be better)...key spacing good for my stumpy fingers...touch screen good... overall performance works for medislike:  POOR BATTERY LIFE -4+  hrs continuous use, set to optimize performance...needs a newer mag-set power plug (the 3.5mm's stick out and are a hazard)..  256 memory is minimal (I knew this going in)  and I find the SD slot card protrudes to far out.recommend you look for  a similar deal but with a better battery, more memory or a better slot.
