How is this not the top story right now? Unlimited storage is game-changing!
I'm currently paying $10/month for GDrive, mostly because of the auto-awesome photo suite that automatically incorporates my full-size GDrive photos and lets me share easily on G+. While I love that perk, it just doesn't compare to backing up my entire family's data for $20/year each... and that's before including the free Office suite for each of us!
If anyone at Google is reading this, you can win me back by incorporating photo deduplication. I have well over a terabyte of duplicate photos that I don't dare delete, but could easily be deduplicated down to maybe 100-200GB. I'm sure deduplication already happens server-side, but the consumer is still stuck with endless copies in disorganized folders.
Sadly, this is almost certainly checkmate for Dropbox. I imagine they'll be acquired by Amazon, which has yet to offer a decent consumer-facing cloud brand and needs the economies of scale to compete with Microsoft and Google. Even then, I'm not sure how anyone can compete with the price of OneDrive alone... much less when coupled with the best-of-class Office suite.
