Now that HP has open sourced webOS and announced their Enyo 2.0 framework plenty of webOS developers have been digging through the code. Given the nature of how Enyo works and it's compatibility with WebKit, we're quite certain plenty of webOS developers will be making their apps available in the Android Market as soon as possible.
One such app that has already made the leap is Paper Mache built by Ryan Watkins. The app allows for access to Instapaper provided you have an Instapaper paid account and it does so rather beautifully. With included features such as offline access, syncing across devices and configurable font, text size, spacing and margins, Paper Mache is a pretty no-brainer choice if you're looking for a great Instapaper app.
Designed to work on Android 2.2 and higher, Paper Mache is available now in the Android Market for free; you can jump past the break for the download link and let us know what you think in the comments.
