I definately use a Palm Compatible device and my 8700. There are too many applications that will not run on the 8700. I read alot of ebooks and I have not been satisfied with the ebook solutions for the 8700. Also I have found that Airlines will not allow me to use my 8700 even with wireless off. This is why i never considered a Treo to have any advantage over a Blackberry. I can though use my Palm and read books, listen to music and enjoy other types of entertainment while on an airplane. In fact, I will be purchasing a new Palm in October.

As for the calendaring on the 8700, it is fine. I have yet to find anything it can not do.
