True. Times are different though. At the time the iPad came out. There was no other comparable device.
In in the market. At the price point I'd get a surface 10 out of 10 times.
A pro device of this nature that does not run desktop apps is not s pro device IMO.
I would be right there with you if the Surface line didn't have so many stability issues. Windows, and its entire culture of fragmented hardware, driver, etc. is really making that product suffer. You know, the screen part of the Surface Book and the iPad Pro are almost the same size. Really very close. Same weight. Of course, the battery life suffers, but, that device is more powerful (potentially) than the iPad Pro will ever be. It's on par with 13" MacBook Pro, and goes beyond when attached to the dedicated GPU component. Though the cost is much higher for that, but, we're talking "Pro" here so it's fine. $2100 is quite reasonable. I'd certainly have bought one if it didn't launch with so many problems.
In reality, this kind of stability is a huge part of what attracts me to iOS. Tons of apps for peripheral use (task management, note taking, planning, design, etc.) that run quite swiftly on a relatively low power device with very good battery life, and very stable. It's highly attractive.
But none of that matters if it can't run the software you need and nobody is making the software you need for the device :-/
