This is an update of a deal I posted last month.

Yowza! The refurbished Barnes & Noble Nook Color, already a steal when it was selling for $179 and then $169, is now a runaway gotta-have-it steal.

While supplies last, Overstock has the refurbished Nook Color for $138.57, plus $1 for shipping. That's after applying coupon code 210574 at checkout. (Note: I have no idea how long that code will be good. It worked as of 9 a.m. ET today.)

That's officially the lowest price I've seen, and a really hard bargain to pass up.

Although I haven't seen the Amazon Kindle Fire firsthand and know full well there's a new Nook Color just around the corner, I have mad love for the refurbished Nook Color I purchased a few months ago (for $179.99, grumble grumble). It's alluringly thin and comfortably light. It feels solid and has that cute little hole in the corner. And it's a terrific e-reader. (Parents, take note: it's especially great for children's books.)

Of course, half (or perhaps three-quarters) the fun of owning a Nook Color is transforming it into a full-bore Android tablet, which you can do on your own or with an N2ACard or Root My Nook Color card. (They're both awesome, though I have to admit a preference for the $30 MIUI version of the latter, which gives your Nook an iPad-style makeover.)

Rooting opens the door to infinitely more apps, including Kindle and Kobo (meaning you're no longer locked into reading books only from Barnes & Noble). The $199 Kindle Fire, on the flip side, probably won't let you run the Nook app.

Will the Fire and Nook Color 2 be more capable tablets? Probably. But I'm finding the Nook Color to be great for books, games, Web browsing, Facebook/Twitter activity, e-mail, and other everyday tasks. And for $139.57 out the door, how can you go wrong?

Certainly not with the warranty: B&N backs its refurbs with a full one year, same as new. Gotta love that.

Bonus deal: Today only, Steam is having a huge game sale in honor of Halloween. Among the best bets: Ghostbusters: The Videogame for $2.49, BioShock 2 for $4.99 (just playing this now, and it's every bit as good as the original), and the Dead Space Pack for $13.59.

Bonus deal No. 2: Also today only, Wondershare is giving away iMate (PC), a $59 utility that rips DVDs and converts videos for viewing on iDevices.
