i have to agree. But here's my rant first. skip to the bottom to get to my point.
my first experience with apple was in the public school system, i think we had apple II's. the interface was unwieldy and slow, there was no right click, i could navigate easier in DOS. Of course since then Mac's have improved, but the interface is still goofy. Easy there fanbois, i'm talking stock interface, not custom. The dock at the bottom is entirely useless, it doesn't close programs, only minimizes them, and doesn't display the active programs clearly at all. Plus the control bar (start bar, whatever) changing to the open program saves about 10 pixels of space, but takes extra hotkeys to return to the desktop and/or filesystem. This all on top of the fact that just about every aspect of the OS is held tightly under lock and key. So if you have any issues whatsoever with a program, your only recourse is to sit on it and spin. Give me Ubuntu or give me death.
On the other hand, apple makes amazing hardware. The iphone is slick, solid state, and speedy for a phone, with a pretty much intuitive interface (not perfect, but it works well enough) Likewise, the macbook pro's are just about the best built laptops you can find, with the best balance of battery life, performance, weight, and the aluminum chasis is just sexy.
If the tablet is even a fraction of what the rumors claim, (at least a multi touch, monolithic, solid state slate) it'll be a new market, and a huge one at that. I'll put up with apple interfaces if they keep delivering on the hardware.
