My gripe is that the original Pi cost $35 at launch and while they have made a better Pi...They have not made a Pi at that price ever again, even accounting for Inflation. Furthermore, increased power consumption and features have added big price jumps to the required Accessories. Now you need miniHDMI adapters rather than more common HDMI, you need cooling, you need more expensive power adapters. a fully set up Pi 1 was simple USB, SD, and HDMI All possible in a $50 budget or less if you had some stuff. Now you are $90 in to run it.
