I like my MacBook Air as well. I wasn't talking to you specifically, just some people in here are making it seem like it's this gigantic lead weight or something when it really isn't.If you're talking to me, I said "noticeably" heavier, as in you can feel the difference. But 3 -> 3.5 is also a pretty large change in percentage terms.
But if you don't care about that then that's great for you, for me I just really like how light the MBA feels. It's not so much that I can't physically carry the MPB or 14 inch.
