Yes and no. From my point of view (user), I can max out and rely on XP9 when simming commercial flights on online networks (IVAO). XP10 is nice to look at, but needs constant testing and tinkering. With settings I like, my top of the line iMac always crashes to the desktop when flying. When flying at home on my 4yo MacBook I have to use XP9. Period. And thats rock solid again. If I wouldn't run a virtual airline, I would not buy XP10 aircraft at this point. If I were a developer I would do XP10 only, because that will be the future market. I still do not understand why XP10 is still so behind its "expectations". Yeah, I know how things are in dev land. But I would still consider it a beta, even it may be a late one. Well, wait and see. Maybe XP10.6 will run on my MacBook. Who knows?
