If you can get ahold of Adobe Ideas APK for Android, you can have a really good vector app. I've been able to save files to the cloud, open them in Illustrator and paste them into Xara.

The drawback is that Adobe killed Ideas so it doesn't look quite right in the font sizes, but if you know where everything is, it's a minor inconvenience.

In an ideal world, I'd like Xara to make their version of Adobe Ideas that saved to the cloud/dropbox/google drive/ or whatever.
