So I've been using this MacBook for about three months now, pretty much every day, nearly all day long.
In this time, I've written three books about CAD for Mac, using software like Adobe InDesign CS5 (which is identical to the Windows version), OmniGraffle Professional (an immature replacement for Visio), FireFox (why can I not zoom the browser window with the mouse?), AutoCAD for Mac (for about six weeks), ARES for Mac (ditto), OpenOffice (once in a while), and I installed Parallels.
I use the MacBook with a PC mouse (Logitech bluetooth), and an external PC monitor for a dual-monitor setup. It's on my 1Gbit network, but only once did it briefly see the rest of my PCs, then never again. My PCs see the MacBook on the network, but cannot open any its folders. I use a USB transfer cable instead.
(The MacBook's goofiest bug: I wake it up, and it sometimes forgets it has a built-in screen; it only displays on the external monitor. One time it locked up so bad, I had to wait 5 hours for the battery to drain; no keyboard shortcut would arouse it from its pale blue screen of death.)
I don't get the awe Mac fanbois have for it; I wonder if some are stuck in the far past, such as the one commenter who talks about "beige boxes" -- a derogatory term used by fanbois to describe the color of PCs from the 1980s. A neighbor across the street praises her MacBook as being simple, "because I can just drag and drop things." (She has never used a PC.) The myopia, deliberate or otherwise, is sad to experience.
I find that Windows 7 is better than OS X in many small details. Here's one I don't get: OS X is based on Unix, and yet I have to reboot it after installing updates, just like Windows; that time-waster is simply unknown on Linux.
I think maybe my problem is with the limitations Apple imposes on its hardware and software. Go with Apple, and you are stuck with their "take it or leave it" attitude. I don't care for the look of the OS X and iOS user interfaces, nor of Apple software. The hardware has its flaws that should not be in products marketed as cadillacs.
A year ago, I bought a 64GB iPod Touch. I found it interesting at first, but then got frustrated with its limitations. Last month, I replaced it with an unlocked Samsung Galaxy S Vibrant for just $50 more, and am so much happier. Stuff on Android makes more sense to me; it isn't restrictive; the UI is better. The many functions of the status bar alone are worth the switch. I can change the UI: imagine that!
But then I'm the kind of guy who doesn't like others dictating to me, which is why I am self-employed. I am a child of the PC revolution; my computing experience will not be dictated to me by someone else. Even a decade ago, I remember thinking that our computing world would be a very scary place if Apple had won the war against Microsoft.
It's g-g-g-r-reat that we still have choice.
Next up: I begin work on my first book about CAD on Linux. I'll be writing it on my PC, not the MacBook.
