Even now there is no software (that I have found) that allows me to use an AFP (apple) or SMB (linux/windows) shared folder from my iPad. Lame, Lame, Gimpy and Lame. I can use ftp, sftp and ssh from my iPad and that's good enough because most of my files are on Linux boxes and are available via ftp. But I don't have ftp enabled on my Macbook and would rather not if I didn't have to.
OK, you are correct it doesn't support 2 methods of communications (or 100 others for that matter)... but from the ipad you can grab files from ftp, email, www, box.net, idisk, google docs. and from your computer you can send it over wifi or via usb sync. Plus your original comment was: And having to use iTunes and a usb cable to get non-music content to and from a wifi equipped device does not meet my definition of easy... which isn't really true.
I don't work for the company but I find all of these methods to be more then acceptable especially for .99.
Honestly this and Jump are the only two apps I've purchased for the ipad. I just wish I could get folders/passwords on the default video app. Don't really want my 5 year old watching episodes of Spartacus instead of Princes and the Frog.
