I could see SmartPhones in 5 years being incredibly flexible with multiple personalities. When you're using it on the go it's an iOS/Android style touch OS. When you dock it to your keyboard/mouse you get a fairly standard Linux desktop. When you dock it to your TV you get something that looks like the Xbox Dashboard. Unfortunately I think this will be limited by battery life. If we can maintain a full day of normal usage that's probably acceptable but realistically 3-4 days is what most people need. I wish my iPhone had the same battery life as my iPad because at that point charging is just an afterthought. You don't have to worry about where the next charge is coming from because chances are you'll be back to your home/work/hotel/etc to charge within 3-4 days.
