My 2 month .Mac trial is coming to an end and I don't think I'll subscribe since the only feature I ever use is iDisk. Having said that, I am really hooked on iDisk and want to know, how can I get by without it? I use a powerbook at home and a PC at work and enjoy the convenience of being able to share files and mount online storage. I have a web hosting account, but it doesn't seem to support webdav. Is there some free or very cheap alternative out there, or some kind of makeshift solution?
