Not that big. :P I can use an iPhone but it is a bit hard so I don't like it.A phone with a pretty big screen for your large thumbs, but can be expensive, is i recommend the Samsung Galaxy
I wouldn't recommend a Nokia Lumia. I own one, and though it works decently, it has been working less and less. It seemingly randomly restarts, and freezes occasionally. These are pretty big problems after owning it for not even a full year.Hey SGTkuzey, After reading what you are looking for , I think the BlackBerry Bold would be great for you. It has a smooth running trackpad, but also has a touch screen. I'm not so sure about the price, but I do not think it is too high! As for me, right now I am thinking about a Nokia Lumia.
Did you decide on a new phone?If BB had some intelligent designers, a good CEO and stopped being a mainstream smartphone wannabe, they would know that 3 ways on interacting with the phone would gather a lot of attention.
