I have an older Surface with front and rear cameras and a pen. I can draw, annotate documents, and take photos just fine while using Windows 10. I can also use the whole universe of software available for Windows. Occasionally I might have to plug in a mouse or attach the keyboard/touchpad cover to use older software that isn't multitouch-friendly. If Apple sold a device which was physically identical to an iPad but ran OSX (with some minor affordances to close the gaps between touch, pen, and mouse input- much as Microsoft has pursued in recent Windows iterations) I'd be ecstatic with it. I've considered trying a Modbook, but the price is a bit eye-watering. Having access to a desktop-style OS would only add to the range of things you could do with smaller devices. Would it be harder to use than an iPad? Maybe.
