We do not know if OP is willing to change his ecosystem and neither did he ask for it.
Actually, I'm looking FOR a change of ecosystem, and that's why I'm looking at getting a MBP. I've been using Windows and Linux desktops and laptops for many, many years now, and I really want to try using a Mac. I like the industrial design of them, and I especially like that they now use Intel processors and have Unix code underlying the MacOS. The last time I used a Mac for any length of time was in the early '90s, at my first job out of high school.
I currently own:
Lenovo T41
Acer Aspire 17"
Acer C710 Chromebook (My Cr48 died)
In my experience, Macbooks and the Mac OS just seems to work. Rarely any hangups, crashes, viruses, the machine does not slowly fall apart on you, none of the stuff that I have experienced with Windows machines. Everybody knows you can get a Windows laptop for a lower price with better specs, but they just do not seem to work as smoothly and the machines don't feel as well built. You pay a premium for a Mac and the Mac OS, and I think the usual lack of hassle is worth it.
However, Macs are not tinkerer friendly. The newer machines are coming with more components soldered in and cannot be easily replaced. I think they want to force you to buy a new machine when you want to upgrade your device, not just switch out the parts. It's probably the same reason they do not have SD card slots on their phone. That lack of flexibility dissuades me from buying more of their products.
Plus you can get some decent 13" Macbook refurbs for less than $1500. The 15" are the ones that get expensive.
The amazing thing about the Mac OS is how little has changed with the user interface over the years. I got my hands on the second version of the Macintosh, the 512K, running one of the early versions of the Mac OS, and it's amazing how easy it was to use the OS without any prior experience. The user interface for Mac OS was designed right the first time. With Windows 8, I needed a training manual. Keep it simple for all of us stupids, please.
Call me a fanboy or whatever, but I just prefer the ease of the Mac OS. I actually got rid of my iPhone for an Android, simply because the features offered in the current lineup of Android phones are better for a cheaper price. But the Mac iOS is so much easier to navigate than whatever bloatware-filled slop Google is pumping out.
All that said, I really want to learn Linux so I can use something more friendly to tinkerers.
