Thanks, micro, I do have an old Acer laptop that I press into service if needed, but I don't really like carrying it. I find the iphone's fine for 99.9% of my travel needs these days, since I don't need it for business anymore. Surprisingly, the iphone's also good for reading books, as you can adjust the text size and the highlights you make get sync'd with the desktop through Amazon. Best for novels, though.
I was thinking I could pop the ipad in my pocketbook on trips and it would replace the iphone and ease Internet use with the bigger screen. That assumes you can use it as a phone. I always try to use my phone in speaker mode, as there is a radiation consideration putting these things by your head, so iphone, ipad, makes no difference and could use a earphone if privacy's needed. Just tossing it around, not ready to buy anything until debt's gone. Unfortunately, that's going to take awhile.
