Non-sequitur. We're talking about features about the iPad 2 and suddenly you're asking about iPad 1 users? Improving a device every generation is common in tech. Everyone knows this.
But personally, I think promotion of a new version - because it's compatible with an accessory which fixes ergonomic issues - is a bit a wrong. The iPad 2 is faster and slimmer .. and has some web-cams built in - but this constant pursuit of 'progress' is a bit worrying. Especially when an iteration provides such (arguably) small gains.
