For what it’s worth, I have considerably less trouble with my P III machine running Slackware and a very minimal GUI environment (read: no Gnome, KDE, or XFCE), than does my wife who runs a 1.83GHz Intel Core 2 Duo iMac.
That said, I certainly envy the sleak, sinewy muscle of a newer, finely-tuned machine. I’d love to try a nice GUI with the console underneath, all developed to work nicely together, taking advantage of that muscle. If OS X could be that (oh, and if I had cash to spare), I’d look into one of these machines, too.
However, the way iPhoto breaks the “just works” credo for anyone but the most placated point-and-clicker (i.e. for anyone who might want to work with the image files directly and not through iPhoto’s UI) makes me cringe. My wife and I hunt around her harddrive looking for certain image files, for instance, to upload to Flickr, and it’s something of a chore.
Give me the responsibility to organize my own photos without “smart” software to do it for me. Granted: we/she could do that anyway, and not import into iPhoto; but since it’s bundled with the OS, there’s an implicit compound statement of “We provide for a wonderful user experience,” and “This is our definition of ‘wonderful’.” You can’t help but wonder what else is similarly wonky under the hood. Or, maybe you can.
Bet that machine would scream with my setup on it. ;)
