I've tried using Asus webstorage, to work on writing at my laptop, then out and about using my phone or tablet, but I can't seem to just save remotely, and end up with lots of un-synchronised versions of things on different sevices, which is what I wanted to avoid in the first place!
Can anyone recommend a good cloud service? Is Microsoft SkyDrive any good? Or Googledocs?
Google docs (or, rather, Google Drive as it's now known) is great for writing on the go. Reason being is that you can create/edit documents direct on Drive. You're not copying it from the cloud to your computer, editing it locally and then uploading it again. It stays on Drive. The word processor on Drive isn't as full-featured as Microsoft Word but it's ample for writing on the go. Once you've got a finished version, download it to your PC and prettify it in Word or whatever.
