I have been using macs since os6 and conceder myself a mac enthuses. I work in an I.S. department with only win nt/2000 and have a pc at home for games. My two home systems are fairly equivalent: g4/533 512mb, geforce2mx 32mb with Mac osX.1 and an athalon 700, 192mb ram and a geforce2mx400 64mb with windows xp pro. I was interested in how these two systems performed compared to one another. The first thing I noticed is the window resizing is BETTER on the mac. OsX appears to be smoother and renders more of the windows contents while it is being resizes. Xp is faster but more seems to take larger steps when being resized. This is only in the finder however, when resizing an internet explorer window, osx sucks. Next I tested Quake3 1.30 with the same settings, OsX 52.7 fps, Xp 59.8, the megahertz myth doesnt really stand up here I guess. Macs are still second class citizens on the network, macs dont have the greatest exchange support and the SBM client built into Osx.1 is slow as molasses. I think the mac gui is light years ahead if xp, I do not think the microsoft people put much effort into the developing a good interface, xp has little icons on the right of the task bar and similar ones on the left with completely different behavior. A huge bar along the top of the start menu that doesnt do anything, and the whole luna thing is just plain ugly. The OsX interface looks great and is more intuitive, with the exception of the folders in the dock that open a finder window as opposed as opening out into a menu, I hate that. I want multiple desktops too like linux. I was more than a little envious however when I plugged my unsupported canon bjc3000 printer into my pc and the driver loaded right up behind the scenes. Osx is a little rough around the edges, but looks cool as hell. I just wish it did not take a $3000 mac to match the performance of a $700 Pc.
