ios fragmentation is not much different. my sisters have the iphone 4. can they use siri? NO. compatibility is something that will never go away. there are certain websites that use .264 codecs and cant run on chrome. newer products will always do more to keep you buying them. its what keeps the tech world moving
um.. thats 1 thing that doesnt work.. the only thing.. an iphone 4 with ios5 can do everything else..
fragmentation problems exists everywhere.. I know this.. Ive dealt with it on my PC due to being an early adopter of 64bit.
I feel like its a much bigger problem on Android.. hence why I had to wait 8 months after I bought my phone for flash support, because Android has no set boundaries.. and Verizon was allowed to throw bing onto it and completely slow down the phones updates.
