I'm not just using terminal. But for those occasions where I need some rare software or to do something that is simpler to do in Terminal, I use it. Macports is brilliant..
I tried Linux first time in 95-96, even played Abuse on it.. Then I've been trying it on and off in the time between. Every single time it has been some kind of nightmarish little problem. Usually with broken drivers. Installed backtrack a year ago on an older comp, and same shit. Got it to work eventually, but was a pain. I mean.. that's just my experience, and I'm by no means an expert.
Now it's like this: When I want something done I use OSX, when I want to fool around or play, windows.
Also, just to recap WHY I think Apple makes better stuff.. They produce a very low number of products, but many of them, which gives them an cost edge. In stead of maximizing profits sacrificing quality, they use better quality components. (FYI all electronics, even a simple resistor, can be bought in many different classes, up to Aerospace standard which is the highest afaik)
Their laptops are built in metal, which of course helps cooling them, and consequently make the electronics last longer. I suspect it's not exactly cheap to machine out, or even stamp aluminum like in my old one, compared to using plastic. I'm sure the chassis is a relatively high part of the price you pay.
Now for the design. I don't care so much about the esthetics or for the logo. I don't care at all about the hipster value. I'm too old.
If you ever opened a mac, you will see they are beautiful on the inside as well, and that placement and design of every component are well thought out.
Performance, is top notch. Sure you can probably shave off 15% of the price to find a PC laptop with equally good specs, but 90% of the time, it will have a worse screen, obscure drivers, run hotter, worse trackpad, worse build quality, be physically bigger/heavier, and a much shorter lifespan if abused.
Sure Apple is evil, but I think less Evil than the pc hardware and general electronics producers who push and have pushed plastic crap, designed to break at consumers for decades. Apple is actually creating a market for quality shit. Samsung phones before iphone were not made to anywhere near the quality they are now.
So even non-apple users can thank apple that they have an easy to use OS and quality phones or laptop these days.
