I work for myself, by myself, so being sweaty isn't a problem for me. But to work, there is a 70m altitude drop, so it's not hard, and takes about 10 minutes, pretty much the same as driving (I'll race my brother sometime). Skateboarding the same distance would suck, the asphalt is bad, and I have 50mm wheels (which is pretty small for a skateboard). I probably take 15-20 minutes to get home.
Not to derail this thread, I also got an iphone 4 2 weeks ago...
