Hi folks, I'm considering a new Ipad( long story, had Ipad1 but had to sell it). However, I'm planning on doing some heavy writing and was wondering if it's more practical to get a Macbook Air? I'm aware of a few apps like Pages and Documents to go, but how good are these? If I did decide to go with the Ipad, I'd definitely get the keyboard attachment. The size factor is definitely important to me, which is why my two options are the Air and the Ipad( ruling out the regular Macbook/Macbook pro lines,and I need the portability so that eliminates the Imac/Mac mini/Mac pro etc). Recommendations? Thanks for reading.
