I’m excited about the newly announced Raspberry Pi 4, especially about the news that it will have gigabit Ethernet that is not tied to is USB bus. I have several older generation ones (I skipped gen. 3) that are in use as little servers in my house. I wish, however, that the form factor was a little neater for cabling. I don’t like having power and Ethernet on different sides. (I probably need some kind of Raspberry Pi server rack, if such a thing exists.)
