@simonwoods I hear you, but my experience coming to the windows from mac has been a bit smoother. Sure, I missed the cross-platform integration on mac initially -- iPhone, mac, iPads all connected. But with my current usage of devices from varied platform (Windows + Android + iPad), Windows fits better. I have realized that, no doubt, applications on Mac are brilliant, well designed. Polished. But they tend to not focus on cross-platform capabilities and stick to just the Apple ecosystem.
Regarding blogging, I have given up on native clients for shorter posts. Web apps allow me to access same, familiar interface from any device. For longer posts, iA Writer is serving me well -- again cross-platform.
