RPI3 is definitely a top-of the line product despite costing $35: http://www.cnx-software.com/2016/02/29/raspberry-pi-3-board-is-powered-by-broadcom-bcm2827-cortex-a53-processor-sells-for-35/ TL;DR: 1.2GHz Quad-core Cortex-A53 (64 bits), with VideoCore 4 GPU. Previous generation of RPI were quite "shitty", RPI1 was armv5 w/ softfp if i'm not wrong. iMX6 and Sitara are "old" Cortex-A8/A9, running at around 1GHz. All of these embedded boards provides OpenGL/ES. The problem is not the HW, the problem is software setup and packaging, mainly due to proprietary binary blobs. eg. https://bugreports.qt.io/browse/QTBUG-62100 >> These are not gadgets, they are cheap boards, that many people use at >> home *and* at work to demo technologies like Qt. > > "Cheap" usually implies "low-end". Sorry Thiago, but this is completely wrong. You can achieve low price by carefully selecting your components and mass-production. Mass-production is actually factor number one.

OK, OK. The industry have to catch-up with Qt... right...
