I'm a software engineer. I only use my laptop (13" MacBook Pro, usually hooked up to a full size monitor and keyboard) for actual programming or other "work" stuff. I use my tablet for pretty much everything else, browsing, shopping, email, games. Heck, I even recently downsized from an iPad2 to a Nexus 7. I even use the nexus 7 for email while I'm at work and the MacBook is right in front of me.
