I wholeheartedly agree. I've been a Mac user for a decade, and I bought my first Mac (a Core Duo MacBook) because of its well-polished Unix operating system out of the box. I loved my MacBook. Its RAM and hard disk were easily accessible and upgradeable; I originally bought mine with 512 MB RAM and upgraded it to 2GB a few years later. I also upgraded its hard drive twice; once to expand its capacity, and again when that drive failed.
Unfortunately for me and many other power users, sometime after the iPhone came out and became successful, Apple started changing from a computer company to a consumer electronics company, and with this transition Apple started actively making decisions that have been frustrating to us power users. Upgrade cycles have become very lengthy, and Macs have also increasingly become difficult, if not impossible, to upgrade to the point that even the Mac Mini featured soldered components. I thought about switching back to PCs in 2013 when my MacBook was long in the tooth, but I didn't want to move to Linux or Windows 8, so I held my nose and bought a MacBook Air, making sure to max out on RAM and get more storage than the default.
Now I'm facing the same decision given that my MacBook Air's AppleCare expired recently and I'm due for another laptop upgrade. On one hand, I still believe OS X is the best desktop operating system out there. Linux, in my opinion, is still rather inconvenient at times, and I find Windows an annoying operating system to use. On the other hand, Apple has shown repeatedly over the past four years or so that it doesn't care about power users and other highly-technical users. Based on what's being leaked, this upcoming keynote appears to be my final straw with Apple. What's the point of having a wonderful desktop OS if the hardware you're forced to use is dumbed-down, compromised, and non-upgradeable?
It would be nice if either Apple offered licenses to run OS X on non-Mac hardware or if a team would work on a Linux desktop that meets the needs of disaffected Mac power users. But I'm no longer going to wait for Apple to change direction and release my dream product: an updated 2006 MacBook or MacBook Pro.
