Looks like they are following after google. Offer freemium until you have a following then axe it and squeeze em for cash. However google makes it hard to find an equivalent alternative. I don't think sugarsync has done that here.
Agreed, actually did a little research and Baracuda's copy.com looks pretty cool, they even have a tool for sugarsync users to migrate their data, they offer 20gb free with 5gb free per referral, no limit. Found the link for sugarsync migration: https://www.copy.com/sugar?r=0ruZ2r
