HP releases Open webOS 1.0, out of beta with video demonstration14
This release follows a couple beta updates this summer from HP. In addition to drumming up developer support, HP faces the challenge of seeing Gram, the webOS/Palm spin-off from HP, stand on its own.
HP has put a lot of effort into this Open webOS initiative, even as it looks like they will re-enter the smartphone market, albeit via Android.
