RAM I've not been too concerned about (for what I do) but the Gigabit Ethernet which doesn't run off the USB is what the RPis really need.

I think that the new built in wifi and bluetooth are wired straight to the SoC on the Pi3, so although that's never going to be lightning fast at least it doesn't eat into the USB bandwidth.

I currently have one of these on my desk to play with: https://www.dropbox.com/s/b0sihpxtqxgd8as/2016-03-02%2013.07.28.jpg?dl=0

It has a dual-core ARM Cortex-A9 processor and an Artix-7 FPGA, all controllable either through C or through the horrible, horrible LabVIEW visual programming bollocks.

It's rather nice, can do stupidly fast signal processing with the FPGA. Shame they cost about £200 (that's student pricing  8-O  8-O  8-O ) plus you need a labview license (~£900) to do anything with them.

I could really do with a job lot of 2 or 4GB microSD cards. Got loads of full size ones that aren't much use now!

I must have dropped and lost at least 100GB of micro SD cards over the years :$
