If you're not in the market for a new computer, then perhaps you should revisit this question when you are. My concern regards present and future offerings from Apple, since I find myself in the position (for the first time ever) of having no desirable options.
It's tough to make choices when you don't have any options.
Well, you do have options, just not the ones you'd like.
I would only expect such a machine if there were comparable PC offerings. Hyperbole like this doesn't help.
Hyperbole makes the point, at some moment we have to make choices about our purchases. Apple doesn't make computers in anything but white, black, or silver so am I boxed in by not being able to get a green Mac? What about options that do exist, like Blu-Ray? Is Apple boxing me in because they don't currently offer a Blu-Ray drive?
There are lots of things I'd like, including a 3G cell-modem (I don't want a dongle) in my laptop and those just haven't happened yet. Am I boxed in?
To a point, the vertical integration of Apple's model means that there will be some limitations, there will be some choices and this has been true since the Mac Plus. Remember what people said about the loss of ADB ports when the iMac came out? Remember SCSI? Or Appletalk?
When I got my iMac, I had to buy a bridge device to make my Appletalk HP printer work with Ethernet. Was I boxed in then? No, I made a choice when I bought the iMac that its advantages outweighed the inconveniences.
I expect people who want a new MacBook to have to make the same choices. It's annoying definitely, and if it were me, I would still include the port or a dongle that solves the problem (similar to the external modem for the iMacs last year), but I don't think this is Apple suddenly "boxing" people in.
Now, if we wanted to talk about the iPhone NDA when it was still in effect, then that's a different conversation. But, even that situation has changed.
