As a graphic designer I HAVE to use both MAC and PC...
I think the best advice I can give you is choose what interface you're more comfortable with.
The fact is, MAC and PC... they're both the same. They both suck, they both crash, they both leave you with headaches.
If you're a veteran mac pro, stick with a mac. You'll find it easier to fix when it all goes to hell in a hand basket. Same goes with a PC.
You think macs are that easy?... yeah, think again. Do you know what to do when your fonts go awol, when you're programs keep crashing and you can only wonder if you have a bad extension? do you know how to rebuild the desktop? MACs have driven even the most mac savy crazy.
PCs, as we all know, are just as bad. The only reason why we hear about it more is because there is helluvalot more of them out there. Viruses, pooched registeries, sloppy installs...blah blah.
No one platform is better then another. in the end, its what you're more comfortable with.
Me? I'm a PC guy... why? cause I've been using em since the old 8088s. before windows... before macs... when MS-DOS was the deal... when I had to boot of one floppy disk and run a program on another. I love the way one can customize a PC, I love the amount of available software, I love how easy and cost effective it is to upgrade it, and I love being able to use more then 32 characters in a filename!
At the same time, I hate installing software that when I uninstall, not all of it disappears which leaves me to go hunting for unwanted files. I hate that when I buy a P4 2000 a p4 3000 comes out the day after
and I hate the fact that windows XP has problems playing some of the classic games like Doom.
I've also used macs for several years now... they're not bad at all. OSX has lots of promise. And it looks really cool too
im sure MACheads will say, they love their interface, they love the way they can change the color of their icons, they love the photoshop power, they love the way the cases look, they love the commercials and they love the RISC based processing.
As well, they can hate the fact that every system has to have a different compiled software for that particular mac. Some things on the beige MACS wont work on the Green Macs, which wont work on the Blue Macs, Which wont work on the Cube MAC, which wont work on a I Mac..... umm, right. The way that OS7, 8, and 9 crashes like theres no tommorow. The fact if one program crashes, theres a good chance your entire computer will go down with it loosing that 4 hours work you forgot to save. The fact that you can't run old OS9 programs on OSX unless you use the os9 emulator that takes forever run. And most of all, Hate when you're mp3s can't contain the band, album and track name cause you cant fit that in under 32 characters for your filename.
2000/XP is great, OSX will be great... both just don't crash... I'll say it again, its what you like best.
heh... yeah, I ranted again... sue me.
