Great UI, great UX. I hate Android, but as Facebook signed ex-Apple engineers and designers, I knew something great would come. And Facebook Home is just perfect.
Most of the beauty, I confess, is due to Helvetica. I hate Roboto more than I hate Android. Especially, when they use the unaesthetic Roboto Condensed (regular width ones are fine). It’s reminiscent of old Nokia phones; the same, cheap look (coupled with pentile matrix display). Terrible, period.
Ah, good old Helvetica. The one we came to love. It looks absolutely gorgeous. Coupled with high interactivity and fluid animations and gestures, Facebook Home is a killer.
The only problem might be that the pictures your friends share are not as good as the ones in the commercials :) Think about the terribly posed, lighted and sometimes downright bad photos in full screen, in your background.
By the way, HTC First doesn’t use the cheap pentile matrix, as far as I can see. It adds to its beauty. The pentile matrix screen (along with Roboto Condensed, of course) is responsible for Samsung Galaxy family’s terrible looks, and HTC First just evades that, with a premium look.
My only problem is that it looks a lot like an old iPhone; the same curves and button placement.
