I find that there are too many haters on this site. Often they don't own, can't afford, or have no real interest in the product that they are dissing and are only trying to get a rise out of folks. The micro-scrutiny is annoying when apps and iOS do not match up with the hardware on day one.
I was just at my local Apple store and spent a half-hour with the iPad Pro. I have been using an iMac with an iPad as my desktop and mobile solutions for a long while. We have a rMB but my wife is using it with her iPad Mini. The screen on the iPad Pro is truly amazing, so is the keyboard. I went back and forth between the rMB's and rMBP's and the iPad Pro, and everytime I thought that the iPad Pro's screen was amazing. The guy next to me had Office Excel open and he as using the split screen option(s), etc. The iPad Pro did seem too big when I first saw it but after holding and using it for a bit, it seemed perfectly fine. For the most part, I like the iOS apps and while I can't use the exact same tools that are on my iMac I am fully functional with an iPad. The only thing that I did not like is the 128GB storage, I would much prefer 250 - 512 GB. Still, with Dropbox and, to a lesser extend, iCloud, the iPads work. I haven't ordered an iPad Pro yet, but I am likely to in the near future.
