I'm not arguing that OS X doesn't have a powerful command line, just refuting the argument that Windows doesn't have that capability. And if a simple extra download or two is enough to bother you then I'm guessing you're not enough of a power user to care about CLI.
Ok, can you point me at a REAL terminal applicationfor windows without installing cygwin plus most of gnome or kde to get a real terminal application? XTerm and putty are freaking horrible to use. They are almost as bad as cmd.exe. Beyond just a terminal, having a built in Xwindows server is also a god send in my job. Windows X servers tend to be flakey imho.
It's not just having bash, it's having a powerful, useful terminal app to use bash in.
I was a windows user. Then I became a full time linux user. Then I moved to notebooks. When I realized that linux wasn't the greatest on notebooks (that is no longer the case today) I moved to mac as it had all the advantages of linux with none of the notebook weaknesses (wireless drivers, poor power management, etc). In addition to those quick advantages, I quickly learned that on OSX I spend more time doing work with my computer and less time working on my computer. I also found tools I feel are better written and supported then equivalent linux tools (and in many cases have no windows equivalent imho). I also gained access to non-free tools such as adobe products that made my job a lot easier then it was on linux.
The only thing I missed was gaming when I moved to linux. I still miss it on OSX, but with steam for OSX, most of the games I want to play have mac versions. I still have a windows virtual machine for one single purpose and that is running the vcenter client.
I love the macbook pro hardware. I love OSX. I can run all those applications I would need from the linux world, plus I get a ton of great OSX software. That said I'm not a fan of apple. I hate what they have done with the iphone, and I'm sure it is only a matter of time before they bring that shit into OSX and drive me back to linux.
