This makes me think about when I used to go to the MacWorld convention in San Francisco as a kid in the early 90's. My mom would take me out of school every year to go (just for the expo hall, we didn't have enough money to actually go to the conference).
I was just overwhelmed by all the different software on offer, and would load up my bag with free samples and spec sheets for software I had no legitimate need for as a 10 year old, but I ate it all up. I would ride the BART home after, just pouring over my loot and being so excited to try the demos at home.
I went a few times after the internet took off, and it just wasn't the same. Who needs demos from an expo hall, when you can just download everything? There was nothing new to see at the hall, everything could be seen from your home just by visiting a url.
I love the world with the internet, but there certainly has been something lost.
