Ok -- I cant believe it took 9 months to get support for iPad Pro keyboard and 12.9" screen resolution. But, that said, with those two improvements this app really extends the power of my iPad Pro in a pretty fundamental way.
I use as my (principal) gui desktop for a Mac mini server hosted with macminicolo.net which provides "virtual monitor hardware" using a unique piece of HDMI graphics interface hardware. I really have a pleasant experience with this, that is both fast and not at all awkward on my iPad.
Ive tried a few alternatives -- honestly, Ive had enough hassles dealing with Parallels (if you ever need support...). But, in a completely objective sense, some of the leading competitors are at least an order of magnitude slower (screens, Im looking at you...).
So, thanks for the recent iPad Pro upgrade, Parallels. Im still a little bitter about the 9 month wait, but I thought Id express that Im happy with the result and share my positive experience with an App Store review.
