Well, i was going to do one of these when i got back, but now that someone's already done it...  

Okay... I will probably still do it  
 That one lacks a bit of style  

I also don't think that comment about the PC already having a cupholder got the appreciation it deserves, so... 
 
 
Seriously, it almost depends on what type of drinks you plan on having most frequently.  I prefer chilled, handled mugs of beer in pint and liter(yes, one liter) sizes full of frosty, condensation-forming brew.  These require shallower coaster style "cup holders".
