All Personal computers, no matter what OS they use are PC: the difference is the OS*: Mac, Windows, Linux, Unix or other operating system.
The "have to take the whole thing in if the Mac needs repair" also applies to windows laptops.
When our Windows Laptop needed repair, we had to take that to the repairer in it's entirety. No pulling out the bits, as the case does not allow easy access. (HP Machine)
Conversely, when our MacBook Pro Battery went BANG! and warped, they got us a new battery (FREE!!!!! Thanks Mr Jobs et al) and the machine kept going.
We have 5 computers all up (2 humans, 4 cats, a lizard and 5 computers. That's normal, isn't it?? ๐ค ): (warning geeky bit) a Windows tower that is a door stop, a Windows laptop that I only use for my security cameras, a MacBook Pro which I love, our ex-editing machine which is a G5 quad tower which we run our studio system on (excluding security cameras because they were Windows only) and a very sexy Mac Tower (quad core, seriously nice) that we got last year to run Maya and Final Cut on. When we need to replace anything, it'll be for another Mac. We have them because they work and are easy to use.
We have not had to install anything or purchase a "Mac" specific piece of hardware for any of our Macs. everything works first time. Conversely, we had about 3 - 4 hours of fiddling, playing and cursing when we had to reformat a hard-drive for a Windows machine - and that was just after we'd purchased it from the shop!
Another big consideration for a Mac lappie is that the newer ones (at least 2.5 years old) have a magnetic power supply, which means if you trip over the cable, it pulls out of the machine. rather than having a machine suddenly land on the floor and go Bang. Poof, big puff of smoke.
I run all my business applications on a Mac OS and have no problems opening XL / Microsoft files or even sending said files to Windows machines. Huge spreadsheets just work.
Even other apps like Photoshop and final cut have transferred nicely between OS.
My way of switching between he OS is to have the mouse r/h for one and l/h for the other.
My husband is writing all his Film Diploma essays on a Mac and there are no issues with his tutor opening them - the tutor uses a Windows machine (I think). Anyway, the webmail is an Outlook derivative and there's no problems with that on the Macs.
I use both OS on a regular basis and do prefer the Mac OS. That's not being biased, that's using Windows machines at work for many years and being grateful to come home to a Mac. My work has involved hard drive / speed demanding files and I've worked in IT projects where I had pretty fast and high specced machines.
Great, the Windows v Mac debate is now on this forum... ๐ฝ
*OS= Operating system.
