Why use BitInstant?

[mel2000]

I have zero interest in buying BTCs anonymously, so why would I use BitInstant->MtGox to buy instead of Dwolla->MtGox, for example? I know the latter combo has a 30 day waiting period, but after that's over, what's the BitInstant advantage?

BTW, when I login to BitInstant at work I get a bunch of deposit options including Walmart, etc. But when I login at home I only get a choice of four coupon options. Same results with MSIE or Firefox. WTF?
