Can't change apple ID. Please help!

I have an iPhone 4 and iPad 2 that share the same apple ID. Its an ISP email address that ends .net. I want to get away from using this address before I purchase my new iMac (when released). I have a mobile me account that I migrated to iCloud some time ago that ends @me.com. I want this to become my apple ID as its the only email address I use. The iPad is mostly used by my wife who uses the .net address. When I try to change my apple ID it says I can't change to a @me.com address. I have read quite a few threads on this and on apple's website. Is what I want to do possible? And if not why not?
To summarise this is what I want
1. iPhone (and new iMac) using @me.com apple I/d for iCloud and app store.
2. iPad using @me.com for app store purchases (but no iCloud on this device) but only receiving .net emails.
3. Both IOS and iMac able to share one synced calendar.

If this is possible can someone explain how to set it up in real simple terms. I guess I'm right in wanting to sort this before I get the iMac so I don't have to change it over after the initial set up.

Does anybody have a solution to this? I'm sure I'm not the first to want to do this.

Well that sucks! Why does apple think we wouldn't want to use just one address? I think it could be much more simple if apple put their mind to it.

But I'm guessing you didn't just change to a @me.com did you? Changing the email address is easy enough as I've done it. It was that I specifically wanted to use my apple email address and you can't which is kind of annoying.

Can't you sign out of your old I/d on the iPad, then sign in using your new one?

I have tried that but when I start the iPad again the old ID is still there. ALSO, I JUST noticed that I added to this thread. I apologize for jacking the thread, I thought I started a new thread.

Not a problem. It's an old thread anyway. Jack away!

Do you have an up to date back up of your iPad on your Mac or PC? If so could you do a factory restore and set up as new again with your back up? If you back up go the cloud, it should work the same way but obviously your going to have to trust all your info is there.
