My first developed (arcade) game "Ski" has had 357 bytes in Assembly, for Sinclair ZX-81 family in the 80's, the player could spend many minutes playing this game. In this context, it is nonsense to see today "Clock" in modile OS taking 15 MB of RAM.

gerbick, I agree with anyone who thinks Android, iOS, Series 40, etc, is good to each one needs.

But it is totally non-technical to say that the OS multi-tasking of Android, iOS, WP7 is better than Maemo/MeeGo/Linux/QNX/Symbian/EPOC. One totally different thing is the speed and smoothness of the combination hardware + mobile OS + GUI + softwares.

Take an Android smartphone with 4 Cortex A15 and 2GB of RAM and it will still be worse in multitasking than a EPOC OS (on a Psion Revo+) from 14 years ago.

IMHO, Android is the worst mobile OS I have ever experienced (I own an excellent hardware, Asus Transformer TF101 with Eee Dock). Many Android hardwares (smartphones and tablets) are fantastic, many Android softwares are great. But Android OS is a PITA.

I really hope Sailfish OS and Ubuntu Phone OS will succeed so in 2014 I will have some choice of smartphone with real Linux inside to buy.
