I'm a big fan of bootstrapping, allow me to add my own data point. I was the typical bored-at-BigCo guy but was afraid to completely jump into startups full time (I have a family). I decided to bootstrap my startup (mobile app) at the beginning of 2010, while working full time for 6 months. 6 months after that I quit my job full time as the income from the startup surpassed my SV engineering salary (made 75K in 6 months). In 2011, I traveled the world for 7 months with my wife while making my 2nd app, and my income went up to 340K. This year, I'm pretty much working ~20 hrs a week and I'm on track to hit at least 600K (already did 300K YTD). No full time employees, no VCs, no board, minimal expenses (macbook + iphone), no hassle.
I have friends and relatives who have done YC, gone the whole fundraising route, etc. Some who are fairly successful, but I wouldn't trade places with them in a second. I'm not saying bootstrapping is better, but if you are like me (risk averse and lazy) then it is definitely a legitimate option.
