There aren't many providers who offer large amounts of storage for free. I for one don't mind the upload limit.
Been using box for about 3 months now and I've had no issues with it. It has a decent android app too.
Plus, Titanium Backup Pro syncs directly to Box. Good way to keep a backup of your apps (Which don't usually exceed 100mb)
