Well I have decided I am going to build an iPhone app. I have a few ideas but haven't nailed down the final details yet.
Of course building an iPhone app requires the apple XCode tools which requires a Mac to run. I am using my wife's Macbook for now but plan on buying myself a 17" Macbook Pro before school starts up again this fall.
For those of you who would want to read about building your own app, check out the iPhone Dev center at http://developer.apple.com/iphone/.
I am also getting ready to head back to school in September working toward finishing up my MBA at Franklin University. I really like the program there and have about half the program to go to finish.
