In interests of full disclosure, I own 2 iPads, and an iPhone 5s. There are 2 more iPads and 2 more iPhones in my household. So obviously, I am no stranger or enemy to Apple.
But I love, love, love, the Surface Pro 3. Really - it is almost everything I have been dreaming of in a PC - plus a few things I didn't know I was looking for. That type keyboard/cover with the magnetic connection and the tilt - so easy. I was reminded of what a pain every other keyboard, including the sleek looking Apple wireless, is to pair up and recharge. Sooner or later the keyboards run out of juice, and it is never convenient to recharge. And the connection - no Bluetooth pairing, so it is instantly on. The magnetic coupling means no fumbling with cables, or matching ports. You literally slap the keyboard on side of the table and it is ready to run.
I find the spacing on the keys totally typical.. I don't even think about it. The kickstand on the back of the tablet makes it stand up at the same angle as would my laptop screen. There is also a touchpad mouse controller on the keyboard, so I don't have to use an external mouse. Or I can just touch the screen. The screen is so readable, with that 4:3 aspect ratio.
The PC has an i7 processor and and 256 gb storage. That means it runs as fast and stores as much as my previous PC, but weighs half as much. Considering I was already carrying an ultrabook, I still noticed the reduction in weight.
The only thing I still depend on my iPad mini for is the 3G connection. If I could put a SIM card in my Surface to connect to the Internet, it would be perfect. I don't understand why the vendors think that a Windows tablet only needs to connect to Wifi. Carrying around an external Internet connection is like constantly carrying a power adcord because there the vendor thought because electric power was available no one would need a a battery.
I also like not having to constantly locate the iPad equivalent to everything I do on the Windows PC. Until the cloud storage vendors came of age I was frustrated by all the backflips I had to do to find and use files. Each app may or may not connect to my cloud storage, and might or might not coordinate with the app I wanted to use.
The Surface Pro 3 is simplifying my life. Windows 8 is still confusing me, but at least I can switch over to the desktop.
