For IRA and rollover IRA accounts I'd avoid this (with its 10% in bonds) in favor of their pure stock index funds.
Chances are most jobs with 401ks will have second-rate stock funds, so you can put more into the bond funds in those 401ks to reach whatever overall amount you want in bonds, while leaving your permanent investments in the best possible stock funds.
That is if you want 10% of your total investments in bonds, keep 100% of your IRA money in stock index funds, while putting 20% or more of your 401k contributions into a bond fund to make up for it.
(This is based on my opinion that having second-rate bond funds does less damage than second-rate 401k stock funds)
