the kobo app store is quite limited, but most apps can be found via google
poweramp I have just looked and that is available from their site to download
the only apps I have had issues with are google ones, but I think this is because the Vox doesn't support the proper android market, there are topics on here for making it compatible, as far as I know this turns it into a standard tablet
dont browse much on it, but I find the built in browser fine, just wish it didnt default to mobile sites
www.getjar.com is the built in app store (its an app that opens that web page), I also have the Amazon app store installed
