I want three to five protruding Palm-style hot-buttons for clicking yes/no, cursor control, selecting and scrolling from lists and launching favourite apps (unlike the iPad's poxy single "flush" button).
I also want the ability to play MPEG2 (unlike the iPad), load&save files freely to USB drives or thumb drives (unlike the iPad), use standard external peripherals (unlike the iPad), take a USB DVB-T tuner dongle so that I can use it as a tablet TV and PVR (unlike the iPad), plug into an external optical drive (unlike the iPad) and, just in case the default OS turns out to be sucky, I'd like the option of loading something else onto it instead, like Windows or Ubuntu (unlike the iPad).
Okay, so the Tegra processor probably rules out Windows, but Ubuntu's pretty good these days, that'd do.
Oh, and I'd like it available right now, please. 😉
