So there has been a recent influx if Mac haters on this forum so I just want to discuss a few minor points of Mac vs Windows PC's.
1. Reliable sleep mode
The killer feature of every Mac which can't be underestimated (and you don't realise how important it is until you own a Mac) is OS X's 100% reliable, near-instant suspend and resume.
Windows PCs have just never had this. Reliability on Windows is hit and miss, and it's nowhere near instant. As a result most people are in the habit of shutting down their PC totally -- or worse, leaving them on 24/7, chewing up power.
The difference between Mac and Windows in this respect is the difference between broadband and dialup internet. Back in the 90s, many people couldn't see the point of paying extra for an always-on internet service, as "it only takes a minute to connect using the dialup…"
I always shake my head in bemusement when I read about Microsoft working on dramatically shortening boot time on Windows. Boot time shouldn't be such a pivotal issue if suspend and resume worked well. Mac users probably reboot their Mac on average about once a month -- and often only to install an OS update. Which leads to my second point.
2. Extremely fast boot times
Rebooting a Windows PC can be such a painful experience that you really procrastinate doing it. Unless you're running on the highest spec hardware, Vista can take minutes to start up.
Mac OS X starts up from a cold boot in about 25 seconds on a current-gen MacBook Pro. As another journalist contributing to the discussion observed, this is not a faked boot speed, where the operating system maker has rushed to get the login window on screen, but delayed loading the rest of the OS. It's a genuine boot-to-usable-desktop time.
3. Apple uses good quality parts.
Aside from the operating system, Mac hardware is usually good quality. Apple's fit and finish doesn't generally bend and creak like the plastic panels on many PC laptops; Apple's keyboards are high quality; Apple selects good quality parts like very good LCD panels for its screens.
You can essentially buy a Mac product sight-unseen and know you'll be happy with the quality of the display, whereas PC laptops are a huge grab bag ranging from horrendous, dim rubbish to spectacular. (I have to admit I personally don't think the basic MacBook screen is of a quality that I would want to buy, but then, I think it's still better than a lot of PC notebook screens.)
4. OS X + Windows is better than just Windows
Ignoring Linux, on a Mac I can legitimately run OS X and Windows (natively, or under virtualisation). On a PC I can only legitimately run Windows.
It means I can use OS X for everything, but if there's the occasional application for Windows I need to use (specialised company application; MS Access; mobile phone firmware upgrader utilities) I can easily do use Windows.
Another of my colleagues said she's found a good use for OS X's Spaces virtual desktop feature -- OS X on one desktop and Windows on another desktop. Of course, you can always pause a virtual machine, too, which means having Windows on-call when you need it doesn't need to be chewing up CPU time in the background.
5. Easier to troubleshoot Macs.
It's usually pretty easy to figure out what's going wrong with a Mac. There are three applications that help you and are all in one place and easy to find in the Applications/Utilities folder:
Last but not least... a true Command Line Interface (CLI). Sure windows has a "Command Prompt" but what control does it honestly give over your computer if Windows "Command Prompt" has to be run in its own simulated environment?
