a) Maya doesn't run very smoothly on a mac. It's hard to keep Maya's windows mimized in a comfortable manner on the mac, and the processing power on it doesn't compare to Maya on a PC.
b) I had a job using a mac, and I spent more time working out problems that would have never occured on a PC. Additionally, I was working with students that knew nothing about the mac and all they wanted to do was to rub touch the thing because "it's so pretty". Because of their overly astetic(sp) design, my work was delayed, interrupted and overall difficult just because I had to use a mac instead of a PC.
c) PCs control the majority of the market, and swapping files between mac and PC is not an easy task (as I found out with the afformentioned) So creating something on the mac meant that I had to do extra work to make it usable on the PC. The OSX support for accessing network drives is apparently hideous. The only way to transfer data between the mac and the PC is to burn a disc everytime you need a file or hook up an incredibly slow USB floppy drive, which is a bad idea because there is a 99% chance the mac is going to not recognize the disk and have trouble accessing it, then it will fill it with files that the PC doesn't need... so essentially, the mac makes less use of the space on a floppy (which we all know isn't much to begin with). When the people you work for can't grasp the concept of a CD-RW, you have to burn a fresh disk everytime which is very annoying, especially when it's only for a few megs of files.
d) Because the market is controlled by PCs, the masses of software and equipment is designed for them. While Apple does a good job of equiping new macs with the latest features, upgrading the old macs isn't so easy, and with a hefty price tag on them, it's not affordable to upgrade every year, or even every other year. A mac costs more than the average college student's car.
e) Many programs have gone out of their way to make the GUIs look like the mac OS, which in my opinion, is way to cutesy for the poor functionality it gives you.
f) Macs come in one look, and one look only, and I personally think that look is boring and ugly. If something is going to be sitting on my desk where I can see it all day, then I want it to look good.
g) There is a popular misconception that macs don't crash as often as PCs... or that they don't crash at all. This is complete bull, you can set your watch to a mac crashing. Then there's the thing with the busy icon... and it hanging... and hanging... and hanging...
The busy icon will display, not allow you to click on ANYTHING, and keep going and going when you try to do things that shoulnd't make it do that. Such as eject a disc, move a file, or close a program.
h) Software side eject buttons only? Have fun with that one. Bring some needle nose pliers and a screw driver along, cause you'll be pulling those disks out at least once a week.
i) The average webpage displays improperly on the mac version of IE. Tables are frequently disfigured, CSS does not work as well and is limited, and there always seems to be an issue with image placement being out of wack.
I'm tired of complaining. :-\
I'm not just another mac basher without reason. When I first used OSX I loved it. Now I hate it like I hate spam.
