The whole Pixel divison at Google are shamelessly plagiarising Apple. Everything, from the event slides and marketing to the products themselves, are in built in the image of their respective Apple counterparts. Yikes!
Indeed, I recently switched to iOS from Android and are very happy with widgets and the swiping keyboard, because I really got used to those on Android. Grouping of notifications, also nice. Let them please copy each other's nice functions, both ways.
It's almost like competition is good
Maybe they are, maybe they aren't, maybe everyone is. You should try and take a moment to think about why you feel the need to defend the interest of the biggest US company. Does Google reimplementing features for iOS impact your usage of iOS in any way? Doesn't convergence help people switch ecosystem and improve competition in a 2 players market?
