While I'm still using Apple's OSX 10.9.x as my workstation OS of choice,
this is mostly due to the fact that it's (still) better suited for my needs than
the alternatives. I didn't upgrade to OSX 10.10, however. OSX 10.10 IMO looks
horrible and doesn't offer anything I'd really need or want as a user,
but instead breaks compatibility with hardware I own and use everyday. Despite
the fact that I have valid reason to stay on OSX 10.9, every week an annoying
Apple AppStore nag-screen appears and tries to force me to update. I'll bet
that sooner or later I will be forced to upgrade due to some breakage of
iCloud services or whatnot. Whether this is due to technical reasons as a
result of poor QA or purely intentional due to Apple
turning into evil Microsoft
remains a speculation, but it surely all just adds up.
Contrary to Apple, Microsoft really has some ambitious plans for Windows 10 and
its accompanying technologies spark my interest. It remains to be seen
whether Microsoft is really able to deliver, but I have a strange feeling that
this time they might really be up to the task.
