suffice

Josh's accessibility fell to near zero the day his PDA phone went blank
His contacts were missing, He had to ask people who were they
Checking email were a hassle, classes were boring because he couldn't surf the net
All he had was a ordinary phone with ordinary functions he uses for reservists.
But after days of using it, he found out that he could text with ease when he's driving, he can concentrate better in class.. erm that's all.
But the point is that, something no frills like this is sufficient, a PDA phone brings convenience but is more than sufficient. Do we, in our lives,need to be more than sufficient?
