We know that there are quite a few new webOS devices in the pipeline, but unfortunately we don't know much about them beyond some random codenames. The folks at GoRumors have tried to rectify this, as a source has told them that Palm is working on a smartphone with a 5-inch display that will launch in three months. It's believed that this device could be the Mansion that we heard about last month, which reportedly has an 800x480 display and no keyboard in sight.
Just about ever since the original Palm Pre was released, people have been clamoring for a full-touch webOS device, and the Mansion could end up being that very handset. The rumored 5-inch size concerns me a bit, though, because that's getting to be just a bit big for an every day cell phone. The Dell Streak, also a 5-incher, seems to be used more as a tablet/MID than a phone, so perhaps that's the same way that the Mansion will be received/marketed? Tablets are becoming all the rage lately, so it may not be a bad idea.
