First thing I thought. If I go to a coffee shop or the park, it's because I want to enjoy that place, not do the same work I could do (better) at my desk. That's an aside, though, the OP's setup is really cool and intriguing.
On the flip side I find it extremely easy to get bored and lazy at home but when I work at a coffee shop the bustle makes me feel more energetic and focused. I work on picnic tables in the park when the weather permits.
