Meg Whitman may have big plans for WebOS, the little mobile operating system that couldn't, but it looks like whatever she's planning doesn't require a large portion of the current WebOS development team. The company has laid off 275 employees in its mobile section. Most of the affected employees are engineers, which makes a lot of sense, since HP has no current plans to offer any more WebOS hardware. The laid off workers will join former Palm executive Jon Rubinstein, who voluntarily left HP last month. Some of the employees may be redeployed within HP, but not all.
