I agree, once you get used to hex there is little need for binary.
For those that don't know, here is a little tip for Binary to hex conversion:
Take a binary number (works for any number of bits, but lets choose 13 to demonstrate):
0b1101101101010
Split it into groups of four bits starting from right to left
1 1011 0110 1010
If there arent a multiple of four bits, then pad with zeros until there are (now you see why I chose 13)
0001 1011 0110 1010
Now convert each group into decimal [base 10] (you can skip this step when you get used to it)
1 11 6 10
Now convert each group into hex [base 16]
1 B 6 A
Finally, stick it back together, and you have your hexadecimal number:
0x1B6A
