I said a similar thing in another comment thread, I agree it's WAY too big of a jump. Especially since a lot of newer companies are already using Google Apps (so they get storage included, unlimited if they have 5+ users) because it let's them scale up and have fixed costs... 3x that cost/mo for dropbox/gdrive on YOUR OWN hardware? $15/u/mo AFTER 30 seems reasonable but going from $0 (30 users) -> $465 (31 users) is odd....
