Now that I own an iPhone, an iPad, and a Mac, I'm really hoping iPhone OS 4 has something to tie these devices together in a better way. I hinted at my desire to just transition work between devices in the pre launch iPad thread, and it's becoming clear many more people are going to want the same. iWork on the iPad is a disaster if you want to also use a desktop at some point in the process. One of the people on MacBreak Weekly said it seemed like things had gone backwards to the days of floppies and no networks in an office, with everyone trying to manage what revision of a file was where.

Between 4.0, and the massive datacenter Apple is building in NC, I'm hoping they push for a more cloud based experience here to just sync everything.

Outside of that, I'll be really curious to see what 4.0 brings to the iPad. It's clear the device was rushed out the door a bit. The hardware is quite solid, but the Apple software side is a little lacking.
