The toolbar was a horizontal strip (or two-column, if you knew the secret) of monochrome icons: the black arrow (Selection), the white arrow (Direct Selection), the Pen tool — that beautiful, terrifying instrument of vector torture — and the Shape tools. Every icon was drawn with a crispness that felt like a promise: we know precision matters.
But the interface was also unforgiving. To adjust a gradient, you had to open the Gradient palette, then adjust sliders, then maybe open the Color palette, then — to apply that gradient to a stroke — click a tiny button labeled "Apply Gradient Across Stroke," which half the user base never found. Zooming was done via a dropdown menu or the zoom tool; scroll-wheel zoom was unreliable. Smart Guides existed but were primitive. Live Trace? Not yet. That would come in CS2. In 2005, the professional design workflow was still ruled by QuarkXPress 6 for layout, Photoshop 7 or CS for raster, and Illustrator for everything that couldn't be done in either. Logos, icons, technical illustrations, packaging dielines, t-shirt graphics, and — increasingly — web mockups for sites that would be sliced into tables.
If you used it then, you remember the sound of the hard drive grinding while applying a complex pathfinder operation. You remember the Zen-like focus of tracing a scanned pencil drawing, point by point. And you remember the quiet satisfaction of watching a piece of vector art scale to any size — business card to billboard — without a single pixel of degradation.
