The main reason I detest the things.
My objection to the iPad, too, tho' I do find it useful in many respects.
For instance ... I would like to send photographs "backwards" to an SD card, I can load them on but don't seem to be able to send others back ? Not interested in iCloud, Sharing, and all that other cr*p, I seem only to be able to slowly e-mail them all to myself to a "proper" computer, after which "I'm In Charge Again."
I've also got a Kingston gadget - thanks to the PPrUne contributor who suggested it to me ! - that allows me to read a USB flash drive, i.e. the one that I have all my passwords on (shush ), but doesn't allow me to edit anything on that stick, so when I change a password away from home I have to remember it and edit the stick when I get home to a PC. Better than nothing tho'.
