The list author says: "Tempted by an Android Tablet? There are some things you should lookout for. Price: You can't beat the prices on WiFi only tablets. They range from $125 to $350.
They are brands you've never heard of and some have lots of experience with smaller units with a propriety OS.
When you shop for one of these new Android Tablets, look for the Android release number. You don't want to be locked into a release that may not be upgraded by the manufacturer. Also, read the description, look for a release date (when Amazon started selling the unit). The most current release for some tablets is 2.3.x (Android 2.2.1). If the unit you are interested in is less than 2.3.x, go the the manufacturer's website and find out.
Find out if there's access to the official Android Market. You will find that some devices have a market that's unique to that manufacturer. Amazon App Store allows for more products."
"This is the unit I purchased. Archos dominates the European market. On the upside: It's a Archos device. There's a huge community forum that provides a wealth of knowledge. It's a very sturdy unit that feels well made. On the Down side: No access to the Android Market. My biggest issue is with the Auto Rotate, it's extremely sensitive and annoying."
