If you have just two funds today (US Stock and US Bond), and you add an Intnl Stock Fund, you increased the number of funds you hold by 50%. If you decided to add an Intnl Stock Fund and an Intnl Bond Fund, you increased the number of funds you hold by 100%. Complexity may not matter yet, but it will bite at some point.
WADR, if 3 or 4 funds = complexity then one should stick to CDs.
