...just a quick afterthought on Dropbox. I still believe that this is one of the solutions of the year for handheld devices. If you haven't had a chance to use this with your iPhone, you owe it to yourself to do so.
I am finding all sorts of uses for this product. From storing short clips to PDF files and other large data files, Dropbox seems to be fast, when hooked up wirelessly over lan and reasonable for downloading pdf files over 3G.
Picture storage is also excellent. What is nice is the ability to obtain these files from either a computer or my handheld device.
