True, but you can get around that by doing the logos in Photoshop at a rather large size so you have pixels to spare. Then it can be reduced to its final size later in another file while the larger size original file is available for editing. The quality loss in reducing files is normally pretty minimal.
I've really only noticed recently that Photoshop can quickly add bevelling and other similar types of effects to type very easily - it's something I want to try out.
