Now my reapberrypi 4 with 8GB RAM is going to be the fastest of my pi collection an I will be able to brows and watch Youtube videos from it without loading delays. Hope it will be almost like an AI Jetson nano. This is small and I can put fix it in my standard case and take it in my pocket to have my power point lectures. As far as booting is possible with a USB drive, it is going to be even more faster. I can store more data in the same usb drive is another piece of cake.
