Dammit, I just starting exploring the 3.0 …

Oh nice!
Quadrupled the SRAM (to 64K) for an additional $0.80. I can handle this.
Also upped the cache and the base clock speed. Also 16 instead of 4 channels of dma.
Saw that DMA item there, did you? 
Also, ordered 4.
Tempted to “+1” your comment, since I did that, too, but then the “+1” reads like “ordered five!”, which I didn’t do.
This explains the price drop for Cyber Monday: get the 3.0 stock out the door. 
Ditto. My Teensy 3.0 still rocks though
