Now, as an application developer, in July 2009, just as Fremantle is ramping up to get out the door and wow people on a Maemo phone, you've been told that your existing application will require porting, and that the platform you're porting to will be obsoleted by the following version. Qt 4.5 had some hacks to get it working on Maemo with qt4-hildon, but Qt 4.6 is the first fully supported version of standard Qt for Maemo, and it only came out last month on Maemo 5 with PR 1.2. So what do you do between July 2009 and May 2010? Do you migrate your application to Fremantle? Try to re-develop it in Qt (or write a new app in Qt)?
