Look you got an avatar of a hooded guy with a windows logo on them, I on the other hand love apple products, I don't think we 'll find much common ground.
You can't blame the hardware when arm cpus have been able to run mobile os's very well for over 4 years. Blame the legacy desktop code that's not optimized for mobility and is on x86. A desktop os loaded with antilmalware, antispyware, and antiviruses, the registry and all that jazz. And like I said I don't consider a mobile unix os such as ios as limited in functionality and restricted. Let's look at it this way, the ipad has been out for a few months and still one would be hard pressed to find apps that are there on the desktop and are missing on the ipad. You also have to understand that a desktop os doesn't mean you can run anything on it that you run on a desktop firstly because on the desktop you have a mouse and some programs don't translate to touch (that's why apple had to rewrite their whole iwork suite for the ipad), and b. because you will be limited by processing power. Actually it's less functional and more restrictive because you will always be taking a punt if any program will run well on it for those two reasons. I would have an app developed for a tablet specifically anyday than one developed for a different kind of os, and if ever an ipad falls in your hands with some decent apps on please use it and tell me if the interface isn't clean, simple, usable and sometimes even ingenious in most of them, as opposed to merely running a desktop app on a tablet where you'll get keyboard shortcuts that don't work, small menus, areas where you have to use a stylus because touch via fingers won't cut it, flash apps that dont work with touch etc. etc.
As for restrictions I have belabored two points amongst others, one that you can jailbreak and do all sorts of hackings to it if you are so inclined, second that an app approval process is there for security and safety which is urgent to mobile devices and doesn't restrict at all (I d rather have that than triple antiviruses running).
There's no point in disagreeing any more, we come from different backgrounds here and we are tiring others who read this thread. Enjoy your exopc I am sure it will have many enjoyable goodies on it.
