Firstly as for your MacBook Air. OSX runs fine with 2GB and shouldn't be swapping constantly for browsing. And not sure why you are complaining that you got 200 euros for a 4 year old machine.
This wasn't true for me on my 2GB 2006 Macbook running Snow Leopard in 2009, so I don't see how it could be true now.
Thirdly a LOT of people thought the iPad was an incredibly feat of engineering to get all that it did into such a small form factor.
Marco is spot-on here, though: many reviewers commented on the frequent page reloading in Safari, claiming (correctly) that the RAM would be an issue in the future. This was the main issue preventing me from getting an iPad 1.
