For down to the basics, get the job done multi-useful, non-flashy, pocket knife handy, carry around device, I liked (and still do) my old 3Com PalmV. I've not been "attached" to any other tech since. Sure, there's some cool stuff out there, but you could drop it like a hot potato for the next cool thing and not look back. Amiga and Palm the only two things I recall foundly. Samsung Galaxy's are definitley cool, but I'm not in to carring a pocket tv/computer.
