I've been wondering about this, too. Maybe I've been brainwashed by the FI community *snicker*, but I took the Vanguard route as well and have liked it, but the no-fee ETFs at Fidelity are appealing since I don't yet have a taxable account. I prefer filling up the tax-sheltered accounts first, so it's kinda painful to think I need $1k at the least, but more commonly $3k just to get started in a real fund if I want to do that at Vanguard. But I really need to double check this, it sounds like many changes have been made. They did remove a good number of Investor shares and replaced them with Admiral shares at the lower expense ratio. I bet this was a push to stay competitive. My $5k in VTSMX switched to VTSAX, I was pretty happy with that.
My company recently switched to Fidelity for their 401k plan. This was extremely annoying to me, and of course they make it difficult for you to do transfers/rollovers to any account that isn't also Fidelity, which pisses me off. "Contact a service representative!" "No, f- you, this is my money and I control where it goes!" You get the idea. I need to roll over some Roth 401k money into my Roth IRA. And I hate calling people.
Yeah, the Vanguard site isn't the best, but it sure beats the ticker puke you get at discount brokers like TD Ameritrade, which I have as part of my HSA. Makes my eyes bleed. Once you get used to Vanguard, it's fine, and if you are keeping your investments simple, you don't need anything fancy anyway.
Dang, I think I'm a little on edge today, this post is coming across a bit sharp. Anyway, Fidelity has stayed competitive, so I'm almost considering making life easier by keeping some of my money with them, too. We'll see.
