Nah, have had to use a powermac at work, I tried to go all trackpad but need a mouse. I did figure out drag and drop is a hold one point drag with a spare finger, but honestly my hands just hurt too much for all that. I can't for the life of me do the 'explode' gesture, it still takes me 3 tries. When I need to get the cursor in between letters to highlight or drag and drop files around I settle on the mouse, its just much faster and precise. For right click I still prefer a mouse as well.
I have adopted it for scrolling instead of the wheel on occasion as repeated scrolling hurts my wrists. On the other hand they also hurt if I use the trackpad for long as I have to curl my wrists at a weird angle to use it, where as with the mouse I can keep my wrists straight.
All in all it is a a very nice trackpad as far as trackpads go, but by far it doesn't have the versatility to surpass a mouse.
Also, delete, home and end keys please? I know you can cmd left/right and I have sort of gotten used to it, its just not as fast. Delete you can fn + delete key but a backspace centric approach to text editing is slower, Usually the cursor is already on the left of a word, so its faster to get to your delete point to remove character than it is to get to a backspace point.
Been a windows user forever, but i have no qualms about hating the mac, but it does have its share of problems. It doesn't know how many bytes are in a meg, it leaves ds_store files all over the place, and I've never seen explorer crash anywhere near as much as Finder does for the apparent crime of trying to open it up and look at the filesystem.
But yes, the unix shell does win a lot of points.
