I don't think it's better: I work with heavy media files and it worries me when Apple makes OSX a bit more stupid every release. But I have faith that as developers we'll make it work (maybe the industry moves to Linux, who knows). But I also LOVE the idea that my mobile phone or some tiny gadget I wear around my neck is the key to my data, and I can rock up to any monitor or use any display, glasses, microprojector whatever. I just see the changes coming, where iOS and OSX are merging slowly. It's too early to say what this is going to mean for pro developers/users.
