Just wanted to give a reference to Lean Branding ebook, which is getting a major facelift in the early release period. It has a whopping 88 megabytes, almost double since previous (pre-)release. It certainly is as interesting read.

Another interesting paperbook comes to horizon. Zero to One is the first book any working or aspiring entrepreneur must read — period.“ - Marc Andreessen

After reading Slovak translation, I can confirm that this book sets up the entrepreneur's mindset and should indeed be the first book read.

The Hardware Startup, pre-release update: this ebook is covering various hardware based business models. Recommended reading for HW startups.
