   No problem.  You will have some degree of "extra" slowdown in a   
   mixed-mode environment, but as long as you're not overly saturating the   
   AP, it should be manageable.   
      
   What I mean is, in mixed mode, the "slower" devices act more like   
   "1.5"[1] devices rather than 1 ... so e.g. 100m throughput with 10 'n'   
   devices is ~10 mbit /device; whereas 100m throughput with 6'n' and 4'g'   
   is more like 8.3 mbit / device.   
      
   [1] - note "1.5" is somewhat of an average, due to all the variables   
   involved with wifi (distance, signal, noise, antenna design/quality,   
   tranceiver design/quality, etc.).  In particularly good conditions, it   
   may be as low as 1.1 -1.2. In particularly bad conditions ... I've seen   
   it spike as high as 2 (but again, contrived "bad" conditions).
