With respect to MSFT today, Google and Box have been offering free unlimited storage for a while now. The difference is that Google and Box required you to spend about more than 40$ a month for a business plan.
My theory is that this latest announcement is really about Google.
I am a happy user of Google products. Even though Google Docs are less capable than their MSFT counterparts their freeness makes up for that.
Now that my storage requirements are starting to push me to pay for a larger storage plan, I am shopping for an alternative.
And MSFT new pricing for storage is going to make me look at MSFT for the first time in ages.
My theory is that MSFT is figuring that there are enough people like me who when confronted with the choice may buy the MSFT plan because it’s cheaper. This may help slow down the growth of Google Docs.
DropBox may be collateral damage.
