What I want is an e-book reader that, when connected to the computer presents itself as both a printer and a disk drive. If I copy a .txt or PDF file over to the disk, it will be available when I unplug the device. By unplugging, it will automatically start indexing whatever changed. When printing, the disk drive will be automatically unmounted and, when done, there will be a PDF file with whatever I printed already indexed. It should make for a good reading experience without reformatting anything.
I have a ton of stuff to read, but I generate a whole lot more every day. Diagrams, spreadsheets, documentation in every conceivable format...
BTW, if the thing has 3G and wi-fi built-in and makes for a passable browsing experience, it would be great. I would love if it presented itself as a Samba server and a LPR PostScript color printer.
It's sure not that much to ask. Is it?
