To Kieron, I keep a tetherable microUSB cable and a charger at all times. I usually carry a spare battery from other Symbian devices, but I don't have one that matches the N900. I'm a power parasite.

I prefer Skype stay active on device and PC simultaneously. I did it just two days ago so I could accept files to the PC while chatting on both depending on where I was. They sync in close to real time, and I liked how I could use the PC for file transfer, and SSH in to bring it into my device. Thanks to GA for schooling me on SSH.
