Android 2.3 vs. 3

[pengyou]

Are all versions of android backwards compatible - meaning will android 2.3 run all of the apps for 2.2, 2.0 and 1.6, etc?

I am looking for a droid tablet that is pretty much a copy of the ipad, in terms of function. Will android 3.0 let me do more than just have a bigger screen?

Quick answer, yes, android is, currently, backwards compatible with its previous versions.
The long answer would state that some apps function better than others, but still, for 95 percent of apps backwards compatibility isn't much of an issue.

Bear in mind that for a lot of the cheaper (sub-$100) tablets, while they may be running Android 2.2, they are typically not running a "full" OS. For example, they won't come with Android Market, and you won't be able to install Android Market on it. It will have it's own proprietary app store so you won't get a "full Android" experience. If you want to go cheap, you will need to accept a certain amount of trade-offs.
