Hot on the heels of T-Mobile's new 4G prepaid options, Walmart has paired with TruConnect to offer a MiFi for "casual users." The service -- called Internet on the Go -- appears to be based on Sprint's 3G network (with no mention of LTE on the horizo...

As you may have read minutes ago here on TechCrunch, there's a brand new iPad app on the market that brings the best of the Reading Rainbow show that many of us loved so much as kids to the current generation of budding bookworms. So it was a real treat to have LeVar Burton, the super popular film and television actor and director who was also -- of course -- the host of the long-running Reading Rainbow show on PBS swing by TechCrunch TV to give us the first-hand pitch on the app that he helped to develop.

Back in 2009, NPR ran a story titled "'Reading Rainbow' Reaches Its Final Chapter." At the time, that probably seemed like a reasonable headline — after all, after 26 years, the beloved TV show was going off the air, the victim of changing government funding priorities. But it looks like there's actually a lot more to the Reading Rainbow story, and its next chapter is starting in earnest today, with the launch of a new iPad app. The app was created by RRKidz, a new startup co-founded by Reading Rainbow host LeVar Burton and producer Mark Wolfe, which licensed the Reading Rainbow name and content from public TV station WNED. Burton and Wolfe came by the TechCrunch office last week to give me a quick demo, and they also laid out their goals for the app.

Late last week, San Francisco and Boston-based healthtech accelerator Rock Health held demo day for its second batch of startups at Practice Fusion's headquarters. The thirteen companies pitched their ideas for making healthcare cheaper, more social, intuitive, and just generally less of a pain in the ass. Even though these companies have a hard road ahead, there are ideas here that, with some iteration and funding, could have have a big impact on the space -- and your health. Check them out here. The accelerator also just kicked off its third batch and the first to be located in Boston. Rock Health co-founder Halle Tecco tells us that they actually just sent seven of these startups to build their businesses at Harvard Medical School. "This is the first time that an incubator has sent startups into a hospital to work," she said, "and we think it will be invaluable for the teams participating." Think we'll call this the new "Rock Health residency."
