I recently purchased a new System-76 Lemur Ubuntu 14.04 laptop. I present my rationale for choosing this laptop over the Dell XPS-13 DE, and my first impressions. I also side-bar a bit about Macbooks, iOS and the rise of Docker as a response.
The pi-top started out as a brilliant idea - a DIY kit using your Raspberry-Pi as a MoBo for under $300. Poor quality control, and a complete lack of customer service and/or support make this an item to be avoided. Spend your money elsewhere - this kit is a dud.
