I mean this to be positive feedback.
Today/yesterday, the Raspberry Pi B+ was announced. I would say the most important 'feature' they added was an improved power plant.
Given how much time Technical Machines spent on improving the power plant of the Tessel, I think the right decision was made. I had early models of the Pi, and the power being flaky was a real buzz kill. The fact that Technical Machines spent the time to do that minute detail correctly bodes well for future designs I think.
I look forward to similar quality/detail on future modules.
