I have just booted into webOS using my HP touchpad. It has been on Android via CM9 for the longest time.
I used to have a pre3 and one function that I really used was doing my sms messaging in my touchpad with my pre3 paired over bluetooth.
I just tried pairing my touchpad with my s3 and without any special settings, and sms works.
I know some of you might not understand what the use is. But when I am at home I sit on the couch watching whatever on my tv, I almost always have the touchpad with me. Doing sms on my touchpad without having to grab my phone is really convenient specially with the card interface of webOS.
Just wanted to share with some people who still have touchpads here and who are still booting into webOS from time to time.
I'm going to leave my touchpad in webOS for now. I find it redundant to have android both on my phone and tablet. I at least for now :-) I have some other use for the touchpad :-)
I have ICS on my TouchPad, but I find webOS works better for me. It seems that the screen resolution throws off ICS and apps don't work quite right for me. I've tried DPI adjusters, but they are still less than optimal for me.
The only time my TouchPad runs ICS is when my 10 year old son wants to play games that aren't available on webOS.
