Dropbox is near the top of my short-list of apps/tools I can’t live without. When I need to move a file from my MacBook to the iMac, it goes into Dropbox icon in my menu bar… and a few seconds later I take it out of the Dropbox on the big computer. Much faster than plugging in a thumb-drive. And it works for files too big to send as email attachments.
And it’s great for files that I use a lot and what to have available anywhere. Sure, I could use MobileMe’s iDisk and do sometimes but nothing is as easy as Dropbox.
And the Public folder is the perfect way to share a big file.
