Microsoft. After spending more and more time with my iPad2 I've discovered the three most important things it has: 1) Lightweight. 2) Superfast startup. 3) Long battery life. If PC manufacturers could make a convertible MacBook Air class machine for $600 that had 7 hour battery life (which is about what the MBA has now) and could start up as fast as an iPad then I think I probably would never use the iPad. That said, what I laid out I don't think is particularly easy for PCs and Windows. There's the whole app store thing, but I find that I spend most of my time in email and the web. Some key apps are important, but frankly I think they'll be on Windows 8 pretty quickly -- especially given it will have an app store with probably 100M customers within a few weeks.
