Windows Phone 7 launched with a dizzying variety of handsets. On closer inspection though, all nine WP7 devices hitting retail space in 2010 feature the same processor and display resolution. So outside of a few notable hardware variations, software is going to be a big differentiator for consumers. That's why LG has teamed up with Microsoft to offer a revolving portfolio of free, so-called "quality" apps to owners of LG Windows Phone 7 handsets. Ten free apps valued at more than $30 will be given away every 60 days via the LG Application Store -- that's 60 apps per year. These are in addition to the free apps already developed exclusively for LG handset owners like the PlayTo media streaming app we fawned over during our Optimus 7 review. Keep it up LG and your mobile handset division might finally pull itself out of the ditch. See the first ten apps listed after the break.
