Naturally, you shouldn’t be left thinking that the choice is between an Apple solution and a Windows solution, as there are alternatives.
Probably the most obvious is Google Apps, which can be used with an Android device to sync apps, email accounts, calendar information and contact details as well as documents from an Android device to the Google Cloud. Over the next few months Google Music will be rolled out around the world, offering a cloud music storage alternative that is expected to dwarf what is already available from Apple.
If you don’t have any interest in auto-syncing solutions and can live without the whole email/contacts/calendar sync, then you might consider taking advantage of Dropbox, a free service (with a paid alternative for larger storage) that will allow you to access and upload data to a remote cloud storage account.
Another alternative is www.homepipe.net, a free or paid service that allows you to share photos, documents and music between your computer (Windows, Mac OS X or Linux) and your mobile phone (Windows Phone 7, iPhone or Android).
The most important thing is to avoid being blinkered into thinking that iCloud is the only solution. As we’ve seen, there are alternatives that are free to use and can be accessed via multiple platforms.
