I use vector images in Paint Shop Pro because it allows more precise positioning.

whem i was a newbie, i used (intelligent thoughts!) your Coreldraw tutorial. As a Coreldraw customer, i used the Coreldraw vectors. At work i use allways Freehand for making logos, but i always used bitmap programs after mi first desktopx zoomer.
Recently i used 3d programs.
For my last works (Noia) i used a bitmap program (Ulead phtoimpact), but i used their vector capabilities, not their bitmap options, an their stiles for make all the designs.
The vectors are good if you need to make a resolution independent design
But, in vector programs, i think that are more intuitive the Freehand interface. Illustrator are more advanced, but you need to do more steeps than Freehand. Coreldraw is full equiped with special effects, but are very confusing (this is my opinion).
The most precise vectors are in Illustrator, but i prefer to work with Freehand. To make skins i have no preferences, i only try the program that can make the 'touch' that i need.

I Use Vector to design everthing. I think people do give Corel enogh of a chance, I have yet to find anything I cant do it it that Illusrtator or Freehand can. I think people get blone away buy photoshop and what I call Filter envey, and dont realize that with diferant effects you can do almost anything in Corel and it is Scalabel and editable to the utmost degree.

i use fireworks...

since i have nothing to show for it, you can see i am still fairly crappy at it

plus i just got it a few months ago and am dealing with a learning curve...

I guess technically you could class Fireworks as a vector application, and that's what I do all of my skins in. It keeps everything nice and clean, and allows for an easier workflow than pushing pixels around in Photoshop.
