I've been disappointed with CPU/battery usage recently. When adding a lot of photos, I have to plug in my laptop--otherwise the battery dies. When uploading a 100MB file on a gen8 Thinkpad: - Dropbox uses 6 minutes of CPU time, basically maxing out a core for the entire upload - offsite scp uses <1 second of CPU, so scp is >100x more efficient than Dropbox - In wall clock time, Dropbox is 4x slower. I imagine their sync problem is very very hard, but but pushing bits up for a large file should be much more efficient.
