You're not alone. If the Macbook Pro is a disappointment -- I suspect it will be -- Apple's ecosystem is toast. I've already ditched all my other Apple devices (almost -- waiting on Nexus) and I'm this close to kissing the MBP goodbye as well.
As much as I hate Microsoft, Windows 10 is rock solid and you have inifinite options for hardware configuration. Apple just isn't compelling anymore. Period.
My wife, not really into macs, recently bought an xps 15. It's been problems for a week now. Dead pixels, scratchy speaker, laggy touchpad, and weird issues with windows shrinking to quarter of the screen. Exchanged it. Same deal except the speakers seem better.
Nothing against windows 10 besides it doesn't work great with high res screens, still can't support a great touchpad, and needs reinstalled each year. The xps 15's screen is a beauty though.
The surface book looked ok but dual core and shaky hinge. Don't need gaming laptops. The rest of them suck. Not sure why dell chose alienware 13 to for its OLED screen debut. That might've been interesting for the xps 13.
So I talked her into waiting for the macbook pro in Oct after installing parallels on her older 13 MBP.
It's not so much Apple isn't compelling, it's just that the competition is even less compelling. That's not to say I don't use windows. I need windows for work programs. I was strictly a windows user since it saw light. I attended MS events, certified in Office from day one, know excel like the back of my hand, etc. I just prefer macOS these days.
