With the imminent advent of these new HP WebOS devices, I think it will encourage folks to take a strong 1st or 2nd look at WebOS.
The HP TouchPad will especially gather attention as the tablet market is pretty hot right now.
It looks like the HP Veer is replacing the Palm Pixi from early 2010. It seems to have a bit larger screen than the Pixi, and it has a vertical slide out keyboard.
The HP Pre3 seems to be a revamped Palm Pre (2). The screen looks the same and the hardware looks identical. The biggest rework for most of these devices is the new and improved WebOS 2.0 Hopefully it is worth it!
I must say though, if HP wants to see WebOS achieve new heights they must get it on some NEW smartphones, not revamped old hardware. The HP TouchPad was an excellent step in the right direction! But it isn't as common of a consumer item as the smartphones.
I hope these devices do well. I really do want to see WebOS succeed as an alternative to Android an iOS. But, time will tell.
