I got one of these ultrabooks and I don't know what to do with it. It's got a touch screen so photoshop is fun but other than that what are these things good for?
Honestly, pretty much everything. At least "good enough for." It should be the computer you just reach for whenever you need something a bit more capable than your phone. Unobtrusive to carry, a long battery life to keep it always available, just enough performance to get you through personal tasks.
Popular as they are with business users, I think that's actually the worst place for them. True professionals can find themselves needing more oomph than ultrabooks generally put out. Good enough for executives who only work in spreadsheets and Slack chats all day though.
