No, it doesn't. With older versions and with Libreoffice I know where to find almost everything. With Ribbon many times I have to Google (for very normal things).
Ironically I thing that for tablets is a good interface.
Thats why I said convenient: a big catalog (no more searching torrents/emule/etc), good download speed (no problems with seeds/peers, dead torrents), no cracking exes, a comunity with forums, mods, etc. Thats the way: to offer a better product.
