For those of you familiar with these two services:
one is in Germany and other in Norway. Both are reasonably priced, but when it comes to functionality, I can’t see Runbox winning. It’s interface is very spartan, buggy, UTF-8 encoding doesn’t work everywhere, it has no calendar + it’s closed source. On the other hand, mailbox.org uses openXchange, has an integrated office suite, a calendar + constant OX updates.
Why is then runbox.com so much more popular online?
