Nothing wrong with it, but if you're still going to create your own UI why not go with nemo, which is much closer to maemo or any other linux distro, i.e. what this community loves.

And if the answer is apps, I'm not sure I like the android app situation more than the maemo/meego one. Ofc there isn't so much choice but in general one can find a solution to a given problem, and downloading an app doesn't involve having to triple-check if your privacy is invaded, or you are being scammed in some weird way. This is purely an opinion though.

Also, I'm sure a FOSS compatibility layer will emerge real soon now, based on libhybris.
