The problem is Symbian has served Nokia will over the years - a standardised mobile OS they can deploy to Nokia handsets (which were low-spec and cheap to manufacture).

That was fine until Apple said "Mmmm look at al that market share - I'm hungry - let's eat"
Then Google said "Hey that looks tasty - I'm eating some too".

It's hard for Nokia to change its behaviour because it worked well a few years ago but not now.

Symbian looks fine from the back - long shiney hair, long shapely legs and a fine little a*se.
Until it turns round and you realise your are looking at your mate's 90 year-old granny.

Time to move on..
