Rapsberry Pi 4 has been released, and it looks GREAT!

Now that the RPi4 has been released, I think we really may have a doable compact solution to portable music production. It is truly a huge improvement of all the previous RPis. The specs are pretty darn amazing:

SoC: Broadcom BCM2711B0 quad-core A72 (ARMv8-A) 64-bit @ 1.5GHz
GPU: Broadcom VideoCore VI
Networking: 2.4 GHz and 5 GHz 802.11b/g/n/ac wireless LAN
Bluetooth: Bluetooth 5.0, Bluetooth Low Energy (BLE)
GPIO: 40-pin GPIO header, populated
Storage: microSD
2 × 4K micro-HDMI
3.5 mm analogue audio-video jack
2 × USB 2.0
2 × USB 3.0
Gigabit Ethernet (no longer sharing bandwidth with USB bus)

In theory, how well could this little guy run Ardour with a USB audio interface attached? I would think the 4GB version should do very well. I have a 4GB version ordered already, but they sell out as fast as they can make them.

Any thoughts?
