<p>It sounds like you should go and try these devices to see what you can successfully use. An IPhone is a two handed device…you need to hold it in one hand while using it with the other.</p>
<p>What kind of cell phone do you use now? Do you plan to use your cell phone for internet and typing emails…? It’s a mighty small device to do so.</p>
<p>From what you are writing, a laptop sounds like the most suitable option for you…as you can put it on a table and use a mouse. The keyboard on many laptops is the same size as a full size keyboard. You can put Skype on it for “calling” others who have Skype also. This might also be a good option for you.</p>
<p>I’m not sure why you would get two new computers (a new desktop AND something for travel) when one laptop would be able to travel with you. If you want to at home, you could hook your laptop to a larger monitor and an external keyboard…but I’m not sure you really NEED a desktop in addition to the laptop you take for travel.</p>
