There is a big learning curve going on here. I am new to an iPad.
I am selling my unused (because I don't like the keyboard Sony Vaio laptop computer and I have replaced it for my own mobile use with an iPad as i love my iMac so much but it's a little big to sit on my lap in the caravan or take down to the beach when Reg is fishing.
Tonight I set up two writing programs on the iMac and on the iPad and I am learning how to sinc the files.

So far I have managed the Storyist software and I'm just going to work with the iWriter files then off to bed.
The iWriter is available from the Apple App store.  I tried a few free programs, A Novel Idea was one of these however the advertisements annoyed me and I deleted it.
Love to know what big file writing software you use on iPad.

I downloaded the Storyist and dropbox software into my iMac computer from the website and I downloaded the Storyist app and the dropbox app frpm the Apple app store for the iPad.  They work easily together transferring files. Believe me I am no computer geek and i learned how to do this in one evening.

I am hoping I can use the same keyboard I use here with my iMac, for the iPad. . So far so good with some advice from my friends above.
