Great call... I actually already have a prototype of the product built... now it's about improving it and selling/marketing it.

Ahh, then its time to move to San Francisco :) I lived in Seattle in 1995 starting in August and was able to survive there only until February - the lack of sunshine was far too depressing for me to cope with. At the time, I helped start an architecture office (HOK) specifically to build part of the expanding Microsoft Campus (I was completely impressed with the MS real estate management pros). So I can only answer based on quality of life, and San Francisco (for me) wins hands down. We also have nature here just a short bike ride away (crossing the GG bridge) and we have world-class skiing about 3 hours away. The cultural scene here is extremely rich compared to Seattle. There are also deals to be had in office space (I pay $1 per s.f. per month) but you have to look (I found mine on Craigs List).
