Well, that was tongue in cheek.
But really, just the opposite-- I'm saying that I'm a total tool who's caved in to the trendy peer pressure of the startup culture. That culture shuns .NET on principal and there's lots of pressure to never use it for a startup.
And if you don't believe there's peer pressure to use a MBP, try going to Red Rock or the Dojo with an Acer laptop. You can just feel people judging you. ;)
