I own an iPad, which I love dearly. I use it for lots of things -- games, email, browsing the web, social networking, writing, viewing photos and video, and remote accessing my PC. The iPad, like all tablets, is a true jack of all trades and a master of some too.
But, try as I might, I canít use it for "real" tasks. While itís fine for writing small-ish articles on, I could never write a novel on it -- and Iíve tried. For some reason, I just canít connect with typing on a touchscreen in the same way I do when typing on a proper full-size keyboard. And I could never imagine attempting detailed Photoshop work on a touchscreen either (well, not without a fine stylus at least).
Maybe itís just because Iíve been using a keyboard and mouse combo for so long that the old control method has become part of who I am when working. I sit down in front of my PC and the mouse and keyboard are there, in my hands without my ever really having to think about what Iím doing.
