OK all you typography snobs out there, up in arms over Ikea’s recent switch to Verdana (google ikea verdana), ask yourselves: If you had one store to shop for all of your furniture, what would it be? Ikea, right.
If you had one font to use on everything you designed, what would it be? Well, you basically have to choose a web-safe, sans-serif font to maximize utility, so here are your choices:
Arial
Tahoma
Verdana
Trebuchet MS
Lucida

Personally, I’da gone with Lucida, but Verdana’s as good as any.
