  For direct interactions (a game menu or similar) getting 
individual characters makes sense; I can't help but think 
Rogue-likes. However for data input (per line basis) or doing 
bulk data/processing, it doesn't work well.

  Something to comment on, a while back when I was first getting 
into C and MS-DOS assembly programming, I did a direct file-copy 
using only one character input/write at a time. A meg sized file 
probably took a minute or so while if I did something as small as 
a 4k buffer it took moments (approx 8000x faster). This was back 
in 1996 or so, still it's obvious the advantages of working in 
bulk.
