The WebOS nuts at PreCentral have received an anonymous tip-off that HP's imminent slate won't be able to edit Office docs out of the box. As much as we'd like to dismiss this as a retaliatory rumor put out by BlackBerry, it emits an unfortunate whiff of truth. While HP has previously made a big deal of the TouchPad's inclusion of the Quickoffice app, it has only said it's "working with Quickoffice" to include document editing, and it has never demoed editing in action. The company has recently been trying to boost its app count, but perhaps it should have put more effort into securing core functionality instead. A glimmer of hope, though: the same tip-off also suggested that at least some editing capabilities will be introduced "via a downloadable update in Q3 2011". Hey, what's the rush?
