ASUS
Some of tha ASUS tabs appear to be Okish the T100s for example. Not really a tab more of a hybrid but cheap and usefull.
Build quality, according to various forums, might be a little bit dodgy. Apparently the keyboards keys stops reacting although the mouse pad continues.
Although I like the Samsung I would be happy to see more a bit competition that is capable of producing reasonable quality material without displaying an Apple price tag.
