I wrote almost this entire column using an iPad which partially answered my biggest question about the device. Can it replace a laptop PC? So far, the answer is a qualified yes. (Scroll to end for my Sunday morning update on why that yes is "qualified.") As a writer and radio commentator, I wanted to see if I could use this device for my work. I knew that the screen would be big enough and that the processor would be adequate for word processing but I wasn't sure about the software or the ability to type on the device. Sure the onscreen keyboard is bigger than what you get with an iPhone or iPod touch, but it's still not adequate for touch typists who want to use it to write long documents.
