my tablet is my short term memory, I use it to remember all the things I would normally forget. liqbase is so helpful
I pull it out at 4am and write odd little reminders for the next day (some are bizarre!)

my tablet is used to design new UI elements (for the tablet).

my tablet is my gateway to linux, it is my primary linux device.

my tablet is my compiler.

I use the gps for knowing where "safety cameras" are *cough*

i read books with it (less recently due to new books being deadtree)

I use it to communicate and discuss with Jacob (hes learning to read and write) so we make lists of things and tick them off.

i don't know how I managed without one
