Is the iPhone 6 or 6plus worth it still?

It was released months ago, and the iphone 6s is coming out in 6 months. Is it still worthwhile to buy one now, and will it last you two years until you get your upgrade, or will it become too slow to use?

It's a pretty good phone. I must say apart from the #Bendgate the phone is really excellent and the iPhone 6s has not been announced yet. There are tons of new things in that phone. If you buy that iPhone tell me and be sure to get a case.Trident Aegis is the est case in my opinion.Otterbox for iPhone 6 is problematic

There has been no announcements for any new iPhones. And I don't see any differences between iPhones except for just the screen size I believe that they just added more battery and resolution because of the bigger screen.

My iPhones never slow down
