Resources for datasets Is there a go to source for searching for data sources? Like a way to ask google, specifically to show data files?

Specifically, I'm looking for data on the number of smart phones and tablets sold in countries around the world. 

Any ideas where I can look?
Browse the following sources to see if you could find them:


UCI ML Repository
OpenML webpage (login required to download)
List of datasets for ML research (Wiki)


Hope this helps.
