Amazon’s Appstore for Android is just around the corner, and according to newly released details about the service, it’s shaping up to be an impressive alternative to Google’s own Android Market.

According to posts at Amazon’s Appstore Developer Blog, Android apps in the Appstore for Android will be easily reachable across Amazon.com, with appropriate titles included in general searches.  There will also be a page of Android app bestsellers. Much the same way Kindle eBook bestsellers are shown, users will see two lists: one for the Top 100 Paid apps, another for the Top 100 Free titles.

App purchases/downloads will also appear alongside Android hardware.  For example, if users tend to purchase particular apps along with a specific tablet from Amazon, these apps could populate the Customers Who Bought This Item Also Bought section of the tablet’s Amazon product page.

One of the most interesting aspects of Amazon’s entrance into the Android app business is the ability to pre-order apps for tablets and smartphones purchased from the retailer. If  a customer buys an Android tablet on Amazon, for instance, they can also purchase (or select free) apps they wish to install and use before the tablet arrives; when powered on and associated with the user’s Amazon account, the pre-selected apps will be downloaded and installed. 

The exact mechanism for this hasn’t yet been disclosed as far as we can tell, however it will almost certainly involve an Amazon Appstore for Android application that will either be preloaded or obtainable through instructions included in the shipping container. Presumably, tablets purchased from other retailers will also be able to use the service with a manual installation of Amazon’s Appstore application loader.

The opportunity to browse, compare and easily purchase Android apps on Amazon’s web site using a user’s existing account will likely be a valuable tool for many, as deciding between applications (particularly higher-priced, paid titles) on a small screen can be frustrating and time consuming.  It should also make reading user reviews more valuable as Amazon makes it easy to search, refine and rate reviews from other users. 

Amazon has not yet announced when their Appstore for Android  will go live.
