Re: Apple's Mac Surge
@ Lorna -
For sure, you're quicker at something you know than something new... almost always. Once you know the short-cuts and your way around, it's more efficient than fumbling. However, that's not an apples to apples (pardon the pun) comparison!
The point about efficency would be: what's the learning curve to get the efficiency? and, once a user has obtained some level of efficency, on which are they more productive?
Back in the day, Gartner used to do some pretty huge studies with thousands of users on efficiency. Apple always came out on top. This had little to do with hardware quality or tech support. It was a simple matter of UI design difference between the OSs, typical UI differences between apps running on the OSs, and ease of interaction with peripherials and other users.
Today, I'd say some of this has eroded. Windows has improved some and Apple doesn't have the tight control on UI that it once did, especially for 3rd party software. (For example, Apple key-something almost always did the same or a similar thing across software years ago... not so much the case anymore.)
But, based on my years of consulting experience, I've seen users on just about every platform, including those who switched platforms. Typically, the Mac users have not only been more efficient, they have done more tasks with their systems. And organizations that have been primarily Mac simply blow away what organizations using Windows have done. Heck, I was working with a decent sized law firm in early to mid 90s that was networked, using e-mail, networked time-tracking and billing, etc. Many of my PC clients weren't doing that kind of thing until years later.
re: connecting to a remote network - I guess I'd have to know what you're trying to do, but I'm not sure why that would inherently be easier on Windows. I suppose if the network is running Windows-centric setup, then it's going to be more straight forward on Windows (if you're talking becoming a network peer). If you're talking things like SSH, FTP, Citrix, screen-sharing, etc. I'd probably beg to differ.
re: fonts in Chrome - Interesting you mention that, because Chrome just (a month or so ago) started properly supporting Google Web Fonts! They have looked great on Macs for years. In fact, I was trying to talk a client into switching their website to some more Windows friendly fonts because their site (and, actually a lot of sites) look horrible on Windows in the most used browsers. No contest here, the Web looks MUCH, MUCH better on a Mac. Only recently has Windows started to render websites reasonably.
