Last night I shared 200+ MBs of pics with a friend without having to upload / email anything. I just enabled the File Sharing in my Opera browser, set my folder and my friend was able to copy over everything directly!
Direct computer to computer file sharing, no restrictions or limitations, and the other person can use any web browser - you don't have to have Opera installed!
For my web browsing experience I still prefer Firefox, but this new feature of Opera - Opera Unite - has got me floored. They've brought the true power of the internet to the end user : It's not just file sharing; I can host photo sharing, chat rooms, games, ....
