I know that iweb will keep working with idisk, and I can use it to post my site somewhere else via FTP, but of course, that hosting won't be free. However, my main concern isn't really hosting a "site" persay, as much as hosting web-accessible files that I (or someone else) can access via your basic web link. I guess the dropbox thing requires that you access your files with some sort of app, regardless of platform, right? (correct me if I'm wrong on that, I'm not a dropbox user currently, so I don't know the ins and outs).
My main thing is that I want to be able to easily put files of any type (not just certain media types associated with specific aps like doc, jpg and gif, mp3 and aif, etc) up on a server and be able to access them via a standard HTTP connection from wherever on whatever platform WITHOUT any special client app, just a browser. So, web hosting, without the website. iDisk has worked great for me for a long time, so it's really irritating that they're going to just drop it. I mean, they just finished their GIANT data center in N Carolina for the icloud stuff, I would think that the iweb/idisk users' data storage and server-side bandwidth requirements would be a tiny drop in the bucket compared to what they're preparing for with icloud, so why not just leave it alone, roll it into icloud, maybe lower the storage amount given for free if necessary, charging a bit for more GB.
Blah, the whole thing irritates the hell out of me. I suppose I'm just going to move to regular old web hosting somewhere else, which will inevitably require me to do my uploading via ye olde ancient FTP, totally UN-integrating the whole situation for me.
