This is the best roundup I found on cloud storage so far: http://www.theverge.com/2012/4/24/2954960/google-drive-dropbox-skydrive-sugarsync-cloud-storage-competition
My opinion after experimenting with many of the aforementioned services? You can get potentially infinite storage using InSync and simultaneously managing as many Google Drive accounts as you like on the same computer.
InSync's biggest problem is that once it finishes the beta stage, you will have to pay a one-time fee to continue using it. I think it is worth it given the infinite amount of space it offers.
An alternative would be Dropbox. You start with only 2GB, which is too little, but there are many ways for you to get free space. You can invite friends, play Dropquests, upload camera pictures and participate in public beta testing. I now have 26 GB, all for free.
I have often benefited from recommendations for Things I Didn't Know I Wanted.
Given that Less Wrong is a community of unusually intelligent, critical, and self-improvement-focused people, I suspect we can generate a pretty helpful thread of product recommendations — perhaps even a monthly thread of product recommendations.
