Got the 1, instantly regretted it after week 3. was too thick and heavy and had no real use for it. Wound up carrying a laptop bag with me and figured it was easier to just get a MacBook. Had to charge halfway through second day, and was basically a giant e reader and portable web browser.
Sold it and my 32gig iPhone 4, and bought a 3yr old macbookpro with the money, and swiped a 4s on my CC.
About 7 months later I won an ipad 2 through work. Started using it more and more, especially at work in order to easily show clients information without having to be huddled in front of a monitor, as well as walking through showroom. The fact it was lighter, and I was always transporting a MacBook, I didn't mind the extra weight over my shoulder. Battery life also improved as I was getting 3 days of usage after 1 charge.
About a year later I won an ipad 4 through work again, sold the 2 for 210 crisp $1 dollar bills and made my way to a strip club. I love the 4 because of the retina display, as well as it unifying the lightning port.
Unfortunately I lost the job that paid in ipad dividends in August, so I'll most likely be rocking the 4 until the air 2 comes out. Thinking about picking up a 1st gen mini for my moms birthday as she carries around a giant toshinba 16 inch laptop.
