I've been used to using my Samsung Intensity 1 (an old phone by today's standards, i know) , but i'm wondering.......if switching to an Android phone much of a big leap? I like to text with a QWERTY set up, are there Android's out there that have QWERTY? Do BlackBerry's have application capability? I'm interested in the Samsung S3 or S4 but i'm worried i either might not like the set up or i'll get lost in the whole mix of things. Any suggestions/advice? Btw, i have an Lenovo IdeaTab, so i am familiar with apps.
