Well those points marked here (at GSMArena) are some kind important, I still looking these phones as mid-range phones NOT smartphones.
Limited apps, well Symbian still getting down on "New" apps, and seems like no much developers want to make new Apps for this OS...And WHY they still on "Locked/Fixed" focus cameras??....OMG
Sorry but Symbian days are counted...
