What will I miss staying on 4.3? topic

I honestly don't want to update to 4.4 kitkat. I refuse to acknowledge googles authority to dictate what I can do with my hardware to that level (the not letting me write to the SD card was the last straw)

Google does not seem to get it that the CLOUD SUCKS with horrible data speeds and capped monthly limits with at home and mobile. screw the cloud.

anyway. what will I miss skipping 4.4 and staying on 4.3? can some of the 4.4 updates be integrated into 4.3?

Thanks!
