I've tried using MacBooks, but they always had issues for me, so I go with (not necessarily new) Thinkpads for the road, but I mostly use my desktops anyway, and that's where I have a Mac Pro and a Mac Mini, which are pretty solid machines. Granted, the Mac Pro was too expensive, if my job did not pay for it I had calculated that I would have built it for less than half the price, but if you're not on a budget it is a good machine.
So, whenever there was new hardware introduced, specifically Mac Pro and Mac Mini I followed it, and if there was a good feature / speed increased introduced I would perhaps go for it (happened once with the Pro, twice with the Mini). But in 2013, it happened. They took their only "classic" workstation with multiple drive bays (I have 2 ssds and 3 hds right now), dual CPUs, PCI slots etc and "transformed" it into a cool looking yet useless to me cylinder.
Then with the Mac Mini, first they took away the option of getting any graphics other than Intel, then in 2014 they soldered the RAM and took away the option for a quad core!!!
So I dread the new announcements, perhaps a new Mac Mini single core. Or with an iPhone cpu... And a Mac Pro that is a cool black sphere... but you can't open it at all for stuff like adding RAM etc.
