I m happy with my t100 (32gb+500gb)
Bought a samsung sdxc pro CL10 64gb and installed a few programs on it.
Still have around 13gb+ on C.
Bought this t100 to be used as a "portable" - to be left inside my car most of the time but still I felt the 32gb version is more than sufficient for every day needs like internet browsing and some presentations.
lastly my 500gb HDD on the keyboard is still very empty.
