If WebOS had a screen like the Evo or Epic (in size and resolution), AND had apps like Barcode Scanner, Shazam, Vlingo, etc, and had a better keyboard (physical or virtual), then sure, I'd stick with WebOs....but I'm not so loyal to stick with Palm until they catch up, I'll go with whatever phone is the best phone for me at the time. At this point in time, I think WebOS has a LOT of catching up to do!!! I don't think the Palm Pre2 is going to do it either.
I'm looking at getting an Epic in a few weeks, but in a year when I'm elgible for an upgrade, if Palm has the best phone then, I'll switch back to them.
