The RSS reader I use, I think it's called TouchFeed is pretty good. The Reddit client, Excavate Reddit isnt as good as Alien Blue for the iPad, but it's not bad. There are some games out there that really show what webOS is capable of like Asphalt 6 and Aftermath. You can put Debian or a couple other Linux distros in a chroot, and run what ever apps you like.
Accessing the developer mode and dropping into the shell you're in ordinary Linux; with Preware you can install a compiler and do whatever you want with it. It's incredibly flexible. I probably still favor my iPad, but I definitely feel comfortable with webOS too.
Just today HP released an updated version of their app store program. The home brew community is dedicated; Gameloft released an Assassin's Crees game a couple days ago (I don't follow the series, so not sure which one). The webOS is dead let's bury it attitude around here is very uninformed.
There's a million TouchPad's out there, and I'm sure most of them aren't running Android. This is different than Nokia's handful of Linux phones that were purchased.
