SugarSync and Dropbox (both free) are two of the most well-known cloud storage apps available for the iPad. Both allow you to upload files or photos from your tablet and access them later on another device, such as a computer or your iPhone. Whether you opt for SugarSync or Dropbox really depends on what you want from your storage provider. While both apps have their strong points -- Dropbox offers better security, while SugarSync has a better sharing model -- those looking for easy-to-use file storage are probably best suited with Dropbox; tech-savvy users who need some additional features will probably be happier with SugarSync.
