I raise the money for the new gadget by clearing out the old gadgets.
I saw an article on tablet v. computer that said the average tablet costs $ 300. I am glad nobody told that to my pengpod tablet, which performs like a champ despite a $ 110 price tag (another $ 14 got me a little keyboard case, which is more fun than a touch screen).
If I had more gumption, I'd design and sell a Linux machine using one of those embedded CPU chips attached to last-year's-tech graphics in a 12" screen for a song, but that sounds too much like lots of work to
sort that out rather than fun so I'll daydream instead.
