Non-photo based images (JPEG, GIF, and PNG) end up looking pretty terrible, with bitmap circles and triangular letters being the worst offenders.
Photos are okay by themselves, but the second you put them next to high resolution text or buttons they look horrible by comparison. If you pick one up or go to the Apple Store you'll see what I mean. Look at NYTimes.com and then look at the NYTimes app. Most of the photos in the app are pixel doubled, but none of the images on the .com are. The app looks a LOT better. But even in the app you notice these hideous, fuzzy leaderboard ads on the right, with high resolution images, UI elements and crisp text everywhere else.
It's like playing a game at 1024x768, but all the UI elements and the chat box are being rendered at 2048x1536. Take a screenshot of Minecraft and then wrap the UI from WoW around it at a super high resolution. That's what it's like.
It's going to force a lot of companies to think about how they architect webpages. The days of quick sprite maps are over. There's going to be a LOT of work out there in the next 2-3 years. I never really learned Photoshop. Good enough, but not great. I learned Freehand and Fireworks instead. That may end up being a bit better now, since a lot of my Fireworks files can be ported to Illustrator fairly easily. Fireworks has always been the ugly stepchild of image editing because it blends both bitmap and vector tools, but it's much easier to port a file from Fireworks to Illustrator because most shapes are vector. The only vector objects in Photoshop are those drawn with the pen tool.
