Tomi Ahonen on his blogspam would make you think that qt and ovi store were cutting edge in "best Development software in the world", while his love for meego is nice, his ******** rants aren't. Every app in ovi needed to be tested vs tens of handsets, programists 'love' that, especially once you go commercial provide support for tens of handsets. iPhone with its dumphone introduced homogenous approach which clearly won. No more worrying about different memory/screen resolution/etc. While it kills competition, it is making dev story short, works on one phone pretty much guaranteed it will on others. Strength of Nokia from 2005ish became its worst enemy, we have 20 different phones + people buy them = so much work for devs it is hardly worth in the end. MS WP idea of standardising (3 buttons etc) was a move towards this. In the long term it could work out. Keeping 3 different OSes (with v3, v5, Anna/belle... and that is just for one of them, expect maemo users whining about meego apps being unavailable, oh wait it is already happening) was just a mess in app-system that discouraged developers. WP, however bad it is, lacks this problem at least
