...except I am hearing murmurs from the Adobe rep that PS CS 3 may actually show up on the Linux platform. One can hope he is not pandering to us as he knows very well that we have Opteron-based Pro/E Wildfire workstations now.
One thing is certain, however, he says that Adobe now develops for Windows as it's "prime" platform. Odd to hear him say that, as there has to be more Mac based GD's out in the world than PC.
Sonds like he's pandering to you and talking out his back-end.
Why would adobe develop for Linux (and what flavor, PPC or x86?)? They would only do so if there was a market for it and at this time the market for Linux in the design field is rather small. Not to say that's not possable, but I'll believe it when I see evidence that it's the case.
As to the PC being the "prime" platform is bunk. I bet he's constriving that "fact" from the time when Adobe announced that PS runs faster on the PC. When they announced that, that was the case. There is no evedence that Adobe develops PS on the PC and then converts it to the mac. Any talk to the contrary is just pure speculation.
Adobe has gone a long way to seperate their programs operation from the peculiarities of the operating system. This way the program behaves the same no matter what platform you are on and it's not limited by the operating system.
As to your comparison:
Since you don't list the specs I was curious to how you got the prices. So... here is the comparison I did:
Dell:OptiPlex GX280
P4 570 (3.8Ghz )
XP Pro w/media center
1GB RAM (2x512)
80GB HD
16X DVD+/-RW
128MB ATI Radeon X300 (w/DVI and VGA)
Dell UltraSharp™2001FP flat panel
1394 Controller Card
Total:
$2,372Apple:1.8Ghz PowerMac
1GB RAM (2x512)
80GB HD
8x SuperDrive
128MB ATI Radeon 9600XT
20" Apple Cinema Display
No 56k modem
Total:
$2,494The mac is almost $100 exaclty more expensive. Of course the PC will have more sheer processing power so that difference is greater. If you move one step up in the Mac line you get a dual 2.0GHz machine for $2,800 and the PC to compare needs a bigger HD which only adds $40 to the price. However, at this point the performance difference is not so great as the mac gets a slight speed bump but mroe importantly, it gets two processors. As we all know, PS is a multi-threaded app and benefits quite a bit from that. How closely these systems will compare in speed will only be known with a test.
I know that once the PC gets into the dual-proc range, prices jump up and PCs no longer have any price benefit over Macs. Agian, speed needs to be tested but I haven't seen anything out there that suggest that today's current dual-CPU workstations can outperform today's top-end dual G5 Macs when it comes to Photoshop.
IMHO once we get into the $2.5k and up range it's more about useability than performance when considering Mac vs PCs.
All this will change quite a bit in the next month or two though. PCs will have a definate performance advantage with multi-core (Intel) and dual-core (AMD) chips coming out but once the IBM PowerPC 970MP CELL chips become available for the Mac (perhaps by Christmas I hope) things may not be so clear-cut once agian. *Speculation* Currently the Mac line is going to see a minor update which indicates to me based off how long the current line has been up and the direction of the market, a much bigger update is comming up next. We'll just have to wait and see.
