This feels a little bit like when I moved from N97 to N8. Some of the S60 5th apps worked on the N8 but the HD games stuff was a no no for N97. How big of an issue was this?
I can understand that perhaps it’s because the hardware can’t handle it. But it just might be because they’re incompatible.
However, there is one tiny ray of hope that you can still install WP8 on WP7 devices (if Phonescoop’s info is correct). The apps may perform poorly, given the hardware requirements, but they may still at least run.
Up until announcement, Nokia will still be trying to push current gen Lumia. How are they going to feel if they knew that new apps may not even work on their phone? :/
On the bright side (as we shall always try to look for one) current user base is small and negligible. There are currently 100,000 apps available for current gen WP. The future of the new base of apps is one coherent core for future desktop/tablet/phone apps that should hopefully see a flurry of even more apps being created for WP and W8.
Update: WP8 apps may work if recoded for WP7.5? Still some effort from the developer side. Like having to make certain apps 256MB compatible for the 610 :/
