Why Windows
Why would I want another OS to run my windows software. Windows does that just fine. And if I don't want to pay for a copy of Windows (or second copy), why would I want to pay for very expensive Windows based software (let alone a second copy).
All I need is to be able to continue my work in whichever environment I'm using. If I create a presentation or video or start programming a web-app in one platform I need to be able to see and use and extend it in the next platform. Each day I use a personal Andriod phone, a work based iphone, a workplace Windows 7 OS, a home Windows and a home Linux (Suse) machine. File portability is far more important than application portability. Failing to see or use the file is far more frustrating than using two or three different applications.
I think Jack's point was Linux has failed because it has failed to present as something new. iPhones and iPad weren't necessarily new (we had phones and tablets), but they presented as something new and were highly successful.
Another OS running Windows apps is not something new.
Please give us something simple, User Friendly, new, smart, and better that seamlessly integrates into our existing work patterns and future work needs.
