I'm really tempted to buy an iPad as my default device instead of my late 2010 13" Air, but there are some apps that just aren't available and have no alternative on iOS, in particular QuickBooks. (I don't do media editing, though I do have my pics in Aperture; most of my stuff is email, word processing, accounting, web browsing, manipulating records (PDFs), etc.) It's one thing to "access" a Mac/PC via VNC, but quite another level to actually try to get work done. I've done it from my iPhone (using TeamViewer) but that's clumsy at best. Good enough to launch an app and look around. Have any of you tried to actually get work done via VNC (from an iPad to Mac/PC) on a regular basis? How well does it work?
