A revolution is happening in the consumer technology world - the PC is slowly, but inexorably, being replaced by the tablet. It doesn't seem to be a question of if a tablet can replace a conventional computer, but rather how long it'll be before PCs are in the minority in both the home and workplace. The battle for the home computer started off as a war between Mac, Windows and Linux, then it became all about browsers (anyone remember Netscape?) but now it's between which mobile OS is going to win out when the dust finally settles. And while Apple may have stuffed it up royally the first time around and let Microsoft steal all the glory, it now looks like it's been playing the long game after all, and this time round its holding all the cards. At the recent launch of the iPad 2 , you'd have had to have been half asleep not to notice that Steve Jobs kept referring to the iPad, and other competing tablets, as post-PC devices. And while we're not in complete agreement with his Steveness quite yet (at the moment you still need to connect your new iPad to a PC or a Mac before you can do anything with it, for example) you'd need to have had your head in a box Se7en-style for the last year to not realise what an impact the iPad has had on the PC industry . The momentum in the market is certainly with tablets at the moment.
