I have an iPad 3G and have to say I love it. I have trouble now going back to my iPhone and reading anything on it anymore, whether it be the web or an email, book, or document. The extra screen real estate just doesn't compare. I used to think the iPhone was awesome for all that. Now I use it to make phone calls.
For a device that's been out for just a short while, it has some awesome apps already. Try out Alice or The Elements or Star Walk just to see what's possible on an iPad that simply can't work on an iPhone.
My kids are addicted to games like Jelly Car and Super Monkey Ball, both apps also available for the iPhone/iPod touch but they refuse to play on those anymore. Now it's iPad or nothing.
My wife is also addicted to hers. She uses the phrase, "prying it from her cold, dead fingers..." a lot. lol. For her, it's mostly used for reading, such as keeping up with her blog posts or web research or work email, or reading books via the Kindle app or Apple's own iBooks.
It's a multi-purpose device that, incidentally, can also read PDF's like a charm, unlike the Kindle.
The battery on that device is impressive as well. I watched three one-hour TV shows through the Netflix app using their instant view streamed over wifi and the battery meter had only dropped to about 85%. I could watch movies or listen to music during an entire international flight and still have some juice left over.
My iPad also has 64GB of flash on it, so I can store a ton of movies, photos (right now 12,500 photos of the kids), and music on it like the entire Lord of the Rings movies and all six Star Wars movies and still have loads of space left over.
Not that everything's awesome about it. The worst part for me is file transfer and printing, something they have plans for with iPhone OS 4.0 due in the fall. But all-in-all, very impressive for a Rev. 1 device.
