Seems if you have an old account and opted for it, you get to keep the 25GB free from before, but for new accounts they are only offering 7Gb for free. Why are they taking away GB while many are instead adding more? And then they want you to pay them $10 to get the storage amount they are still giving away free to others?
I suggest to look elsewhere as Google added 10gb and now gives you 15Gb free($5/mo gets you 100Gb paid acct). And Copy gives 20gb free if you sign up through a referral link(https://copy.com?r=VjyqiP), with another 2GB given if you tweet about them, and another 5gb for each friend friend you refer who signs up(offers $10/mo for 250Gb paid acct).
If they still gave a free 25gb, then it would be good for personal use, but 7GB? Yeah right, go for Gooey's 15Gb(+integration with many chrome apps/some FF), or Copy's 20-27Gb(no chrome/FF integration, but come on 27+GB free!). I will have to have of a 200+gb account in a few months so copy will become my paid cloud as it is the cheapest per gig(remember desktop apps only allow one account to sync so 2 accounts would be a pain). If you don't need a huge paid account, I suggest copy for personal use(big space & fast), else if you need a paid account, gDrive is the best free second choice I've found so far(enough space, but slow)
