Wow.
As long as they aren't all stuck on Gingerbread or before. That experience would get much worse. Of course, Jelly Bean still rules and KitKat is growing too.
Actually, I wouldn't mind having the same specs and dimensions of an iPhone 4. That was one of my TOP 5 fav phones ever. It did so many things so well with a beautiful screen and long battery life. If an Android OEM can come up with similar specs to iPhone 4 but with KitKat and for under $120, I wouldn't mind getting it. The prob is most 3.5 inch displays don't have a resolution that comes close to iPhone 4. The cam and battery life is usually awful too. GPU is also quite weak. The only worthy compact Androids come from the Sony Xperia Z Compact series.
The iPhone 4/4s were some of the BEST iPhones and smartphones ever. I still see many people use them. You couldn't really fault them in too many areas except maybe for the iPhone 4's GPU with simple games like Subway Surfers starting to lag and the cam is nowhere close to the current iPhones. But iPhone 4 specs is as good on having a BASIC phone doing BASIC tasks as most cheaper Androids out there. If you are not into gaming or a shutterbug, iPhone 4 is still a great BASIC smartphone to use.
