I don't know any person who still uses USB flash drives. Everyone I know, including I, uses SD or SDHC memory cards. These are readable on all devices (mobile phone, PDA, e-ink e-reader, netbook, laptop; oh and I don't own a PC!). USB drives can only be used with computers, not with e-readers or PDAs, so what's the use of them?

If I read a legal paper and electronic copy of your book for free (the electronic one must be readable on my 6" e-ink gadget) and I like it, and then you release the book as public domain or GFDL 1.2 but not 1.3 or later versions (but if the book is very great then I may settle with Creative Commons or other similar licences as well), then I could pay you whatever you want for the book, as long as what you want does not exceed a monetary amount I have in mind right now and aren't going to tell you. In short: You don't need to have copyright, you don't need to force people to support you for writing books. If your books are good, people will come to you to support you without any laws, copyright, or other things.

The best e-reader I have ever seen is BeBook.

Have you tried gobby?

After university I had some interviews with some software houses for employment, mostly because it was "the normal thing to do", but I didn't like their working environment. I wanted to work from home but they didn't agree, and the salary wasn't good. So, I refused to be employed and instead started my own software business which is very successful, and I have three collegues from my university. I cannot understand why other people go to become employees for a boss when they can start their own business. I would expect other graduates like me to go to interviews after university because "it's the normal thing to do", but I cannot imagine in what terrible situation one must be to actually agree to become employed for someone else.
