We own both an iPad and a Surface. The iPad is a gaming/media/e-reader device while the Surface has replaced my laptop giving me tremendous portability and access to all of my Windows programs (especially Office). Nearly all of the useful apps on the Apple are also available for the Surface. When I go for another tablet it will be a Surface-like device.
I’m in agreement with you. I have an Ipad, a kindle, an older iMac which I just replaced with a multi-touch Windows8 machine, a Dell laptop, a Google laptop and a MacBook. My next “work” computer that I purchase, will be a Surface Pro.
