Saw this thread on Google. It is possible to root it but it's only recommended for certain serial #s. Still not a big deal because it's easy to install Marketplace without rooting it using Android SDK and the abd.exe DOS program (tutorial: http://gunnersbarn.wordpress.com/201...ook-premium-7/
) That way you don't risk bricking it by flashing the ROM on a device without a great track record for rooting.
SlimeME market is horrible and doesn't have most of the basic Droid apps; ES File Explorer, etc. It's useless. Before I got Marketplace on it I just went to Google and typed "[appname] APK" for everything with Apps from unknown sources enabled.
Yeah the hardware is what hurts it the most. Battery life goes down significantly over time and you're dealing with 512M of memory.
