As an IT professional, I stay away from Windows products if possible. The OS is poorly written and does not have the end user in mind. Some things work and some don't. Not an intuitive OS when compared to IOS. Android is going down the same lines.
What kind of "IT professional" are you? Apple is a good choice if you have individual users that need to use a Mac only product. However, there's a reason why Microsoft dominates the OS market. It is a much better OS for running and managing a network. Apple can't compete in that market because they just don't get business. Actually, I think they just don't care since that's not the market they want to compete in.
Now if you're just talking about Windows 8, then I agree the interface is a huge problem for a power user. I find that it's just weird and somewhat reminds me of switching from DOS to Windows 3.1. Windows 7 is a great OS imo. Windows 8 is better in speed and security ... but I hate the interface. There's a reason why the guy in charge of Windows 8 was fired. I have no desire to push 8 onto my company so we'll stick with 7 probably until 9 comes out.
I've heard blah reviews about the cheaper Surface but I've heard some really good things about the more expensive one that run an actual version of Windows 8. It has capabilities not found in any other tablet. I'm also interested in the new Dell tablet. It has a lot cool features that Ipad doesn't but I haven't looked real close into it.
