One thing I've found with my iPad is that many apps aren't as essential as on the iphone because the web browsing experience is so much better. A lot of good iphone apps also don't have iPad versions yet and in my case, I just got my iPad to use at home so haven't bothered with a lot of travel/location-based ones that I have on my iphone.
The one that I would still recommend is Instapaper. You install a bookmarklet on your browser and can save items to read in the app on your iPad/iPhone later. Couldn't live without it. There's a free version with not quite all the features I believe.
I've also just bought GoodReader and think I might end up using a lot. It's a PDF and document reader and can link to your Dropbox account, Google Docs etc. (btw if you use DropBox, there's a DropBox iPad app too). It's 59p at the moment.
