Thanks anyway - very useful to know
On to another question, as I don't want to start a new thread....
I'm using a trial of PS CS5 at home currently (I use CS3 at work), and as I'm in the market to give adobe an unreasonable amount of money

I want to make sure i'm buying the right software...so back to the question..
Should I buy photoshop or illustrator?
At home I'll be doing light design work such as logos, and will likely never do anything with photos. I've never used illustrator, but I hear good things. Is it a similar tool set, and will the skills I've picked up in PS transfer to AI??
Thanks again!!,
Photoshop and Illustrator share tools, but are fundamentally different.
Photoshop is a bitmap graphics editor. It allows you to edit the matrix of pixels that make up an image. It is essentially a modern, high resolution mosaic tool.
Illustrator is a vector drawing tool. The core tools generate curves, lines and shapes that are defined mathematically. Export your illustrator file as an EPS and open it up in a text editor to see the PostScript code.
Photoshop "draws" with dots. Illustrator draws with math. Photoshop works at a fixed resolution. Illustrator drawings using vectors can be scaled up or down without loss in quality (because they are math)
Illustrator does support the placing of images. Photoshop supports vectors. But the core philosophies of the programs should be kept separate.
If you are editing photographs, or otherwise manipulating pixels Photoshop is the tool of choice.
If you are designing logos, setting small amounts of typography, or doing technical drawings Illustrator is your tool of choice.
Photoshop is (in my opinion) an easier program to work with even though its toolset and features are far larger than illustrator. This is because the majority of tools within Photoshop are based in reality. The toolbar is full of tools you may have used before (airbrush, paintbrush) and many of the effects and processes are rooted in traditional processes (unsharp masking is a technique taken from the stat camera for example).
Illustrator is more difficult because the interface metaphors are less familiar and more abstract. You cannot find or use a "Bezier pen" in the real world, as it does not exist. The bezier pen also requires a learned facility with the mouse (a symphony of clicks and click drags) to use it efficiently and quickly.
Photoshop is by far the most popular tool, because it is used by many many industries. More than just a photo editor, web and interactive designers use it for a layout tool, animators and video editors use it for special effects, 3d modelers and animators use it to create textures, etc.etc. There are few creative businesses that do not somehow intersect with this tool.
Illustrator has a much smaller (actually shrinking) market share. It is still primarily used for the creation of print-based graphic artwork like logos and logotypes and the creation of single page layout projects.
For the types of work that you are looking to do, however, Illustrator looks like a good choice. Download the CS5 demo and see what you think. The good news (I suppose) is that Adobe has not really been pushing Illustrator development, so if you can buy an older version of illustrator for cheaper (CS3 or CS4) do so. The differences between the versions are not tremendous and for the work you are looking to do, the new features are negligible.
