Right now you have a lot of choices for Cloud storage, the first player to the game being DropBox and they have integrated seemlessly into so many services and a lot of people use it naturally. Right now there are several cloud storage services out there: Microsoft SkyDrive, Apple iCloud, Google Drive, Box, & DropBox.
I for one shifted my iTunes and current Apple services to the iCloud, it just helped me access my iTunes from my other machines mainly and get my music on the cloud. SkyDrive interfaces with Microsoft very well but thats about it for me, doesn’t really fit my needs since I barely use Microsoft Office. Google Drive is very Google Docs oriented, a bit on the stiff side for me, stills its new and I haven’t had a chance to try it out completely. I haven’t really tried Box which is another independent service. DropBox has all my needs covered for now with an excellent updated online interface, works perfectly with Android & iOS, and does exactly what I need between my machines. Below is a comparison chart between the different services, the comparison done by Gizmodo, and the only major difference is that DropBox is a bit too expensive and I think they should bring down their prices but it is their core service in this case. You can also check out a more detailed analysis at the link below from Gizmodo, for now I’m sticking to DropBox.
