>>>Your 286 never had a "proper" Windows OS.

>Basically this thread is about an impressive smartphone with proper Windows and I'm wondering why that wasn't done in the first place. Hence "proper" Windows. Why was a whole new OS needed? Especially when it flopped in the market and ceded the OS to Google. All the expensive malarkey getting apps to work on smartphones with Rube Goldberg combinations of strings and counterweights could have been shortcut by using the familiar prevalent OS on the MS phone.

There may not be one single reason but there were some significant factors that made proper Windows OSs of a few years back unsuitable for mobile phones:

- Necessity to run on ARM processors - low cost, long battery life
- Quick boot and resume from sleep/standby - quick enough to answer an incoming call
- Needed touch interface rather than mouse

This is just some, there are probably lots more.
