I usually use a laptop now and my wife often only uses her iPad. Currently, there are limitations to the iPad (only a virtual keyboard or small add-on keyboard that are hard to use with my fat fingers). But, most of the things I do daily on my laptop can be done on an iPad or iPhone for that matter. I have the HubPages app on my iPhone, but I wouldn't want to type a Hub with that keypad. Since I do not plan to purchase a new device for at least a year or two, I'll wait to see how things develop. But, I will keep an open mind to the options as the devices evolve.
