I'm a .net developer and iOS developer there just isn't a market for writing win 8 mobile software, at the same time the lack of apps is what is keeping me away from a win tablet. A bit of a catch 22, I know. But the iOS market is now so congested, that it's no longer a money maker either.
I do love outlook. Even on the RT. I'm thinking of going to the dark side as well but annoyed by one aspect of win 8. It's great for tablets, but running all apps full screen on dual 27's is annoyingly stupid. And vertically aligning them does not help (split). Great on tablet, horrible on PC and laptops. Maybe it's just me, but the desktop side was not thought through and needs a bit of work. And writing two separate apps, one for desktop mode and another for metro also is a stopper since the frameworks are vastly different (still .net but wpf is different).
I am thinking Microsoft will focus quite a bit on software for apple (office & RDP are examples). Their osx version of RDP is 50 times better than on the PC. It even does retina scaling properly, but on win 8 it's awful!! It scales down, but not up. So DPI is screwed up. DPI is another thing they need to fix, by the way. Half the elements are Too small, the other half is too big (on retina, and yes, I've tried the new 8.1 scaling). The other issue is their release cycle in osx software is 10 times faster than on windows. For instance RDP went through 4 iterations. RDP for windows is still 3 years old with only a minor update. And RDP is huge now that cloud computing, cloud workplace are becoming popular.
I ordered a Mac Pro. LOVE apple, but still looking back and seeing if anything good is on the windows side. I can always cancel before feb.
What is enticing you to switch? Would you do phone too? I think Nokia needs to get their act together and release a different looking phone. All their phones look identical.
