Technology Issue

A very exciting development occurred recently – I got an iPad!! No, I did not pay for the new one – this is for the purposes of teaching. Gregg has had one for a while but I never had my own. I have been trying to be more productive and not having to haul my laptop around has certainly helped a person who already carries a massive bag, a diaper bag and frequently a child and a half!! But the minor problem has been that my home laptop and school computer are both PCs while the iPad and my phone are not. So the question has been – how can I work from both a PC and an iPad? iPads lack MS Office and powerpoint. Thus far, I have found Dropbox and an app called Documents to Go Premium that supposedly work together very well. However, I have not found the courage to pay the $17 that the latter needs. Nor the $20 that people recommend for QuickOffice. Instead I got the free app Onlive Desktop and am using it for now.  Any suggestions anyone? Have you worked with any of these products? Do you have an iPad app you would suggest?
