Today is eBay's Analyst Day, and we're watching the webcast to glean any important bits of info for you. Stay tuned for more throughout the afternoon.

"I'll pay you back next time." How many times have you heard that? PayPal wants to change all that by allowing person-to-person payments via your mobile phone. If you are a PayPal executive and you're buying a case of wine in Napa Valley, no need to tote a bunch of cash -- just let your friend pick up the case on his credit card and you can PayPal him back a couple of bills in the parking lot (before putting the half-case in the trunk of your Mercedes sedan, of course). I'm psyched, because next time I go to the Goodwill outlet, and my friend Larissa and I go diving for funky thrift items to re-sell on eBay, we can combine our loot (it's less per pound the more you buy) and I can pay her back instantaneously. Or how 'bout this: garage sales! It's brilliant. If I could use my PayPal account at garage sales, I'd buy so much more.

This is working now, and a new feature that was just released: text-to-pay. There's a demonstration of how it works; the presenter buys a Walk The Line DVD from his phone with his PayPal account (a UPS deliveryman brings it immediately -- yeah, you're cute, eBay). It's great, but you could already buy that DVD with your cell phone (yeah, you had to call the 800 number and tell them your credit card number, etc. - but still. Not changing the world). You can't use your credit card at a garage sale. Your buddy doesn't have a credit card acceptor when you split the check. That's where PayPal makes a difference, in my opinion.
