Hi, I'm considering either Ipad or a tablet laptop, but the cost of the latter may be too prohibitive. So I have some questions i hope someone can answer for me. Will I be able on an Ipad to: -Mark up pdf files (underline passages, make little notes in the margins) and then transfer the file to a Windows PC with all the markups preserved? -Be able to read Word, Excel, PDF documents. Can I edit them or mark them up? -Use some sort of VNC client to access my Windows computer? -Access my files stored on dropbox? Thanks!
