Mail, Safari, AirVideo, ABC tv, NPR radio app, GPS Drive HD spoken turn-by-turn, Maps (which worked fine in Canada, and even in obscure parts of Maine where signal was crappy or non-existent), Pandora, Corkulous for random musings & creative ideas, Flipboard even it is 1.0 now, and of course Dropbox which rocks. LightTrac is awesome for planning on location shoots.
Hulu Plus is a joke. ABC has it all worked out in comparison. Anxious for Comcast to come through with their promises to release a similar streaming app for their subscribers (the only thing that may keep folks paying their hefty fees). Chances of Comcast pulling this off? 25% in my estimation, hope to be proved wrong on that.
Big Wishes? Wireless camera tethering. A wifi or bluetooth camera connection kit that lets you preview/control your camera on the fly (a real camera, not just one that will control your iPhone camera). Currently the Eye-Fi cards do not work as the iPad won't let you set up an ad-hoc network. And it seems ridiculous to have to buy ANOTHER wireless data wire service like MiFi to accomplish this...
Anyone who says the iPad is just a consumption device is an idiot. It has replaced my laptop since I set it up...

PS: Photos is awesome, even with its severe limitations. I use it for a quickie portfolio for clients, or to show comps. Also, handy to dump photos while on vacation to empty media cards. I love the one-click to add any image from anywhere (Mail, web, etc). I also wish there was a screenshot app like Skitch that would allow annotation... I use Skitch constantly all day long.
