If you're pondering a new phone or Windows device, Microsoft is keen to help out at the moment. First of all, it's offering up to $250 of store credit for your well-kept smartphone or tablet, depending on the model. That trumps the $200 iPad trade-in from last year and would get you a deal on any product (sold in participating stores) and not just the Surface Pro 2 like last time. Redmond also wants to prod those looking to get Xbox Music by offering a no-contract Nokia Lumia 520 or 521T-Mobile version gratis with a one year, $100 pass. That's a phone we'd likely pass on at the regular price, but if you're looking to get Xbox Music anyway, "free" definitely works. The trade-in expires on March 2nd, but you'll have to think faster to get the Lumia 520 or 521 -- that deal's over on February 17th.
