No, no, you misunderstand me. Tablets are absolutely superb at consuming content. I make no bones about that. I have an Android phone that is used almost exclusively for consuming content and I picked up a TouchPad to surf the web with on my balcony. I just don't get the people here trying to act as if they're productive with their iPad in a way that is impossible to do on the Fire.
I think "laptop replacement" isn't talking about me and you, it's talking about my mom who spends all her time on facebook or email and casual games and doesn't do a whole lot of other things.
I can use google docs on my iPad, I can type emails, I can consume. That's about all 80% of home computer users need generally, so that's why it's a laptop replacement. Not sure you'll have a lot of luck making a presentation on a Fire or updating a spreadsheet, but those things are doable on an ipad even if they are a little cumbersome. (80% obviously made up!)
