Krisse: Thank You So much:

1. Sorry I didn't give an example of how I'll use it. You are correct that it will vary.
2. As to the phone booster, a number of companies sell external packs that one can use to recharge their phone/device. I believe there is one available.
3. As to the Linux question, I am a technical person, somewhat familiar with Unix/Linux, and I guess I was wondering what is 'left' out. I am sorry to see that a true Java SE VM is not available as of yet. I hope this gets solved.
4. As to my ebooks, I have a number of technical ebooks that are 400-500 pages long, with some graphics (but no scripting). I read a thread where PDF's can be about 100 or so pages, and this would really be too small for me. What can I say, today's programmer's are not as smart as yesterday's. In the early 1980's, Wordstar (my word processing program of choice) could edit documents thousands of times the size of RAM (and we are talking 64K!). I'm getting old.

Thanks again.
