For the $100 it cost me to upgrade I am very happy with the ipad 2. I immediately noticed the speed improvement. The ergonomics of the thinner form factor and the convenience of the magnet-activated turn-on are great.
Same here. I bought an iPad 2 on launch day as my first iPad. I couldn't resist the refurb pricing on the original iPad, so I ended up selling the iPad 2 and sticking with the first generation. I don't game much so the experience has been nearly identical between the two devices for me. Wasn't worth an extra $200. =P
Don't try to get justification for your purchase from others. If you enjoy it then enjoy it and dont worry what other people think. If you've made a mistake then return the device or learn to make more informed decisions like going to the apple store and playing with the iPad 2 until you're convinced its right or wrong for you.
Nope
Great decision to upgrade!
