One other thing OVI should have implemented is being able to purchase apps on your desktop for example by bank transfer or anything, then having them enabled on your account so you can easily download them later on your phone.
Again shouldn't be that difficult to implement?

There was some news about Nokia making deals with many carriers so that you could purchase something and it would show up in your next phone bill. This not implemented for N900 Ovi yet, or someone got this option?
