No. Please, PLEASE understand that you will not notice a difference from one technology to the next unless it is a nearly complete &/or new interaction or technology.
Did you notice the difference between Wireless G and N networks (Wi-Fi)?
Did you notice the difference from last years 2.0Ghz Intel processor to the new 2.2Ghz?
What about 2gb of ram vs 4gb?
Audio CD vs MP3?
Dolby surround on DVD vs Dolby True HD on Blu-Ray?
5.1 home theater system vs 7.1 home theater?
The general answer is NO. On paper most things, especially computers, needs graphs and charts for people to 'know' there's a difference. If your computer is only upgraded every 2-3 years you will notice the upgrade most of the time.
A lot of us were happy with our original iPad even when the iPad 2 came out. Know why? All they did was offer it in white and add a camera. The better A5 chip and ram let Safari remember web pages better but other than that... what else? Nearly nothing. But now the 3rd gen iPad has a ton of upgrades and we see the difference now. This years discussions sound exactly like last years and more than likely, they'll sound exactly like next years as well. What will be different? The iPad 2 owners who didn't upgrade will go "Oooh, ah!" while 3rd gen owners will go "meh."
The new iPad is easily worth $100 more than the iPad 2. The camera is substantially better than the one in the iPad 2. More ram, retina, quad-core graphics and the same battery life. Resell value will also be higher. Some of you actually talk like there was no upgrade to the unit at all.
