Photoshop isn't really incredibly memory intensive anymore.
What a completely nonsensical statement.
It makes perfect sense.
Back when Photoshop 2.5 was out (on 4 floppies -- back when we were running win 3.11), people had like single-digit memory sizes, and the OS used pretty much all of it. Opening any moderately sized image used all the resources you had pretty much.
Back when Photoshop 4 was out (Win95 era), we still had very little RAM (most people having 16MB or less), and the OS used all of that too. Opening anything still used all your resources.
Back when Photoshop 7 (CS) was out (early win XP era), we still had around 128MB of memory, and XP's core uses more than 128MB, yet again leaving you with hardly any resources. Opening anything even remotely big (high resolution scans, drum scans, etc) or doing anything more than than the very basics still quickly brought your machine to its knees.
Nowadays, Photoshop CS3 opens on ~90MB of RAM which basically is nothing at all for any modern computer. You can also get 4GB of 800MHz DDR2 for as little as $70. I you have 4GB, and have Vista running + Photoshop CS3 open (nothing else, like in other scenarios), you still have over 3.5GB of RAM left to work with, without making use of any virtual memory (or 1.5GB on a box with 2GB) In the previous scenarios, you had a
negative amount of RAM left after the OS loaded (anything you could use, was due to memory paging i.e. virtual memory), whereas now you have entire gigabytes left on commodity PCs! Even opening a 12 megapixel RAW file and adding a couple extra layers only uses an extra ~1% of my free RAM. Even an old box running XP with 512M of RAM could handle it. And processor wise, even a several years-old P4 will suffice for over 90% of tasks. In all those gigabytes of RAM free left, not only you can load a LOT of images at once, and do complex things with them, but you can actually multitask! Something I wouldn't even have attempted before (it would have been excruciatingly slow). I very often have Photoshop open at the same time than other apps that use hundreds of MBs of RAM and it works great.
Long story short, save for a couple exceptional cases/uses, Photoshop isn't one of those monster processes that brings any computer to its knees anymore.
It was a perfectly good point. I didn't think anyone wouldn't get it.
