I just noticed that Microsoft's live.com has gotten pretty smart. Go ahead, hand it an algebraic equation and watch it solve for X.

That's pretty snazzy, eh?

But wait! There's more!

"More?"

Much more!

MS has launched a SMS search service much like Google's (46645). You can now text search, queries, and yes - algebraic equations to 95483 (WLIVE) and get back the answers post haste. Follow that link to see what all 95483 can do for you (here's a few: local search queries, reverse phone number lookups (!), area codes, word definitions, math calculations, spell-check, etc.)

I imagine this will be great news for any kid with a cellphone taking an Algebra test.

I'm particularly excited to be able to do reverse phone lookups. Next time someone calls me and I don't have their number programmed in my phone, I can find out who they are by texting the number to WLIVE.

Despite the way I feel about Microsoft, their mobile guys are constantly impressing me.
