Saved with the link. Notes from 2007 to 2016 are mostly the page's own words, so this is probably an excerpt.
After nearly a week with the new HP TouchPad and webOS 3.0 my overall impression is that the TouchPad is less than the sum of its parts. There is nothing the TouchPad does that the iPad cannot except play Flash video (sometimes). I could not find one feature or function that was significant or compelling enough to take the TouchPad seriously compared to the iPad.
