My point was that Sony's focus (as a brand) was never the pro photog/designer or even the computer user, they were and still are in the entertainment/music business.
Which does not stop them producing very good professional kit. So not sure what your point is! Canon don't just make cameras you know, does that make their kit less professiona/good/focused as cameras are just a small part of their business?
Plus you seem to forget that Sony are also attempting to end the Canon/Nikon dominance of the camera market and seem to be doing a pretty good job of things so far.
Apple is about design and experience which used to start at the hi-end/power user, including designers, scientists, etc.
It simply happened that the original creative software was first designed for the Mac, as at the time PCs were way inferior to Macs. Hence the Mac became known as the creatives platform, as for a few short years you couldn't get some software for PCs and people kept using them once they'd started. And for many years not many people outside of the creativce industries used them.
Unfortunately, everyone is becoming too diversified to please specific users, even Microsoft has Zune and Xbox/Games.
Actually, Diversification is the only way to please specific users.
Just like Apple's new trackpad or the Wacom Cintiq is an entertainment device!! I think you've missed the point. It's an interface, not an entertainment device. So it may be brilliant for both work and play
