Most people buy new computers once in a while. It's quite the news that you can't simply re-install retail Office on your new PC. I think it's actually the first time this happens with mainstream retail software.
Most people who buy a new computer get Office installed on it by the store when they upgrade. The full version of Office isn't cheap - for sure - but most people don't get the full package. They get Home & Student, which is $120 boxed - it's cheaper if it's bundled with the laptop.
Also: when was the last time you bought a laptop with office bundled, and it came with a CD that you could use to install Office on other computers?
