I picked up a 32GB HP Tablet from the firesale and have been running the stock WebOS.
In the last few weeks some of my kids have complained that the new gmail interface is no longer fully supported by the WebOS browser. Basically it won’t load unless you switch to the basic HTML version. And then you lose the gtalk chat capability – apparently the killer app for teen girls.
This morning I had one of the college kids install Android Ice Cream Sandwich (v4.0) on it. It went smoothly and works well with the exception of the camera and microphone. At the initial bootup, I connected the tablet to my google account and apps started to automatically download to it.
What is very nice is the install doesn’t overwrite the existing WebOS and can boot back to that if wanted.
