I came here to say basically what
@Telecaster said, although I might make an even stronger statement to say the 0.25% fee isn't worth it at all, especially if you're not in a very high tax bracket where some extra losses could be written off against ordinary income at a high rate (and you won't get losses that large with a relatively large balance.
However, one counterpoint to Telecaster's comment is that if you DO want to keep the taxable account at Wealthfront then also keeping the IRAs there might make sense if they will coordinate the accounts because that would avoid issues with negating the losses they harvest when you invest (or reinvest dividends) in the IRAs. If you move the IRAs then read up on the wash sale rule and either invest your IRAs in investments that Wealthfront doesn't use or turn off automatic dividend reinvesting and be very careful with what/when you buy in the IRAs.
Again, I'd ditch wealthfront for Vanguard, Fidelity, Schwab, or Etrade (roughly in that order) though.
