Not only that but if you make a mistake, and render the eMMC unbootable. How would you fix it without an sdcard ? Short answer is that you can't. But with an sdcard, you'd insert the "emergency" card, revert the changes you made, then power cycle the board ater removing the sdcard. viola! problem solved.
I would also highly recommend getting a 3v3 ttl USB serial cable. They don't have to be the FTDI $20 cabled. One like this: http://www.ebay.com/itm/like/231721779803?lpid=82&chn=ps&ul_noapp=true would work. Think we picked up 2 off ebay for less than $5 including shipping. You just need make ABSOLUTELY SURE the serial side is 3v3 logic. Or you risk damaging the beaglebone's processor.
