I can't remember exactly in what order UX concepts of Maemo/WebOS/Meego came in, but they all had the concept of cards, implemented slightly differently (eg. Nokia N9 and Pre 3 were both released-into-void in 2011 :)). It's amazing that such great products basically never got released (Nokia just sold-off the mobile division to Microsoft, and Pre 3, with Palm already owned by HP, was scrapped days before release).

I loved my Palm Pre 3 gotten off eBay (though I had to hack it to enable Serbian 3G connection, and I put together a Serbian Cyrillic keyboard layout too :): cards and swiping on the home button when editing text (to go left or right by a character or two) were monumental for me. Along with the full keyboard, the first (and last) time I didn't hate typing on a phone :D

Edit: it was probably 3G and not LTE at the time :)
