Roland TR-8S vs Yamaha EAD10

I saw that video of the guy walking down the street with this thing in his hand like a mini boom-box, headphones on, creating some sort of beat on-the-go. I should have known then that this wasn't quite what I was looking for. I really want to like this thing, but the sounds I am looking for aren't quite there. I mean, they are, but everything is so buried in menus that just when I think I've found what I wanted, I loose it in another instrument

So, it's pretty fun, you're just having a blast there but what I wanted to also do is I wanted to record a beat with our studio mics, these are $10,00...
