I use Linux at work and I think without having a deeper technical understanding of the OS, you're going to struggle with security patches etc. which Windows can do. Also device drivers can be notoriously difficult to find for new hardware you plug into your laptop. The open source community is growing though, so Linux is probably going to be right up there in a few years time.
We have a Debian server here, though not sure what it hosts nowadays (other than a VPN between our house and DH's best friend's apartment). My netbook is Windows XP. My laptop is Windows 7 with Windows XP Mode and couple virtual machines (Windows Server 2008, Windows 7, and Ubuntu).
