Frank, I read your review several weeks ago with great interest, and you've sold me on the PPU clip, which looks perfect for one of my upcoming trips. I meant to thank you earlier!
It depends on the trip. If it's for a conference, I bring my iPad and my Kindle. If it's for a holiday, maybe I bring an iPod Touch but often not even that. I'm a gadget freak but like to have breaks. I also tend to worry about my electronics when I travel so not having them makes me more relaxed.
I have a new portable back-up charger for small devices being sent to me next week. Very small, very lightweight. I'll try to put a review up as soon as possible on my website.
That is....after I do the Tom Bihn product reviews that need to get done.
