Nokia's View MeeGo is targeted on high end phones (superphones or

computers ) Symbian OS is targeted on mid-range phones

(smartphones

) Upcoming N8 is a mid-range phone! Series 40 / 30 / 20for low end ( phones )

No na ve development environment Java ME!

Qt Supported Phones?

Symbian^3 devices support Qt by na ve (Nokia n8,etc)

What about "old" Symbian devices? Don't have any Qt support by default Qt app includessmart installer! Smart installer checks that if device does not include

Qt, it will install it automa cally! S60 3.1 and later!

FUTURE?


40/41

Thoughts on future:Ba le for Developers

Nokia+ Qt looks very promising+ Hardware excellent+ Market leader: zillions shipped

devices+ Open- Qt under heavy development- Fragmenta on?- MeeGo's future?- Ovi Store and Ecosystem- Success in USA?

Android+ Lot of support from non-

Nokia manufactures+ Good programming

environment+ Open+ Ecosystem- Fragmenta on


41/41

Thoughts on future:Ba le for Developers

Apple+ Ecosystem+ One OS, couple devices, no fragmenta on

+ App Store, millions of applica ons+ Mature programming environment- Apple's control for everything- Close OS and rules
