How difficult is it to use the internet on a blackberry?

hey guys so here's my situation: my family is switching to AT&T and were all getting smart phones i own an ipod touch (im 16)... so i am used to using the touch screen internet on that with a large screen. *i also find it unnecessary to get an iphone for this reason. so im thinking about getting either the blackberry bold, the samsung jack, samsung epix, or the moto q global *my point being anything that is shaped lke a blackberry how hard is it to use the internet? i know the small cursor thing acts as a mouse but im worried that it'll be too frustrating since i am used to my ipod touch screen.. well, the size of it but i also know that so many people have blackberry;s that it cannot be too difficult. what do you think? and any suggestion on which phone to get? thanks!
