This may answer one of my all-time biggest needs for a portable.
So, now that the power supply is integrated into the mini, here's my idea.
First off, I hate laptops. They're the ultimate compromise. They're slow, expensive, heavy, bulky and the battery life dictates carrying a power supply anyway. But when I'm on the road, I often need a portable computer to setup in a hotel or whatever to import, review and edit the day's work. I thought of a mini, but they were always way too slow, still needed a power supply and of course the most obvious problem is the lack of a monitor.
Second part, I love the iPad, sort of. In itself it's not powerful enough to do any serious work, but it's great for everything else. It also happens to run one of the best VNC apps out there, iTeleport (formerly Jaadu), as does the iPhone. Its battery life and ease of charging make it a great ultraportable for lightweight work.
So now, I'm thinking I may have the solution. Maybe, but I need it tested first. The cheapest iPad and the cheapest Mini together connected via VNC over Internet sharing could solve the whole problem for me. Portable power computing when needed, and ultraportable tablet when not. And it still has firewire, unlike the smaller macbooks. The only issue I can think of is the resolution problem of a headless mini- in the past you needed a monitor plugged in for the video card to output anything over 800x600.
Any input here?
