Headline from the Wall St Journal. The author thinks iPad is the Windows killer. Me, I think Vista (and Windows 7 is little better) killed Windows. We stopped buying PC's when we could no longer get Windows XP on them. We buy iPads to avoid Windows 7.
Windows is a walking flapping security hole, takes forever to boot up, runs slow, eats up too damn much RAM and disk space. Which accounts for the popularity of non Windows things like iPad.
