This really needs to be done. Android is on par with iOS now and probably more popular with computer savvy people. Android has a better dev kit now so it's not such a pain. It's also MUCH easier to sync anything with android via numerous methods. You can even use samba with Windows.
I'm a paying customer (multiple licences) and I love the application but not having a droid version will make me think twice if you're going to ask me to pay again when you release Version 6.
