If you've ever filed your taxes on an iPad, you know Intuit's TurboTax app is free to download, but that you'll have to pay up once you're ready to submit those returns. But, in an effort to promote its newish apps for Android tablets and the Kindle Fire, the company's giving the entire number-crunching cow away for free -- at least through this weekend. Just download between tomorrow (Friday) and Sunday and make sure you start your taxes before Monday (it's okay if you finish them later). To be clear, this includes both federal and state-level taxes, which you'd normally pay for separately for $29.99 and up. Another quid pro quo: this won't work on handsets, even though the Kindle runs a customized version of Android 2.3. If you own a tablet it should run smoothly on Honeycomb and Ice Cream Sandwich, though. In any case, to those of you who've been putting off your taxes, happy downloading, procrastinators.
