I'm curious to get the input from you or someone else that has done the necessary research on Android tablets as to which the "best one" is supposed to be.
The best one is the one that does the most things you would like to do, in a stable manner.
Right now, for most people, that would be the iPad. Apple has their shit together, and that just cannot be said of ANY Android tablet maker or even Google, at this point in time. They just passed something like 100,000 iPad-specific Apps in their store. I have friends who are anti-establishment types (big Android fans), who have published an iPad app, and won't even consider producing an Android version. As new developers, they want to be paid, and pragmatism is a very good idea.
Sorry, but until Google steps up and blesses a reference standard like a Nexus Tab or something, the Android tablet market won't have any "best" tablet. Until Google steps up with a real tablet SDK and a good emulator, the hurried and shoddy Android tablets will always take a back seat to the iPad.
On a side note, the history of Android and iOS devices should be considered when looking at this market disparity. Apple started with the tablet first, and shrunk it down into a phone. Sure, the iPhone preceded the iPad to market by three years, but the tablet touch interface was being developed for the better part of a decade before it was shrunk down for the phone. In both iPad and iPhone/iPod renditions, the devices were clean-sheet from the ground up. Apple got it right on the tablet, and then worked to get it right on the phone. The delay in releasing the iPad was most-likely due to needing the silicon to catch-up, so that the user experience wouldn't suck. Apple has fast emulators for both the iPad and the iPhone, and targeting either device with a common codebase is very easy.
Android, on the other hand, started out using the Microsoft Windows Mobile reference platform for hardware. The initial designs (pre-iPhone) looked much closer to Blackberries, than the now-omnipresent iPhone/Touch form factor. The first Androids were hobbled by their MS-designed roots with goofy memory management, and all Android manufacturers are still paying Microsoft for the privilege of using their crappy design. Android tablets grew out of this, with the added technical problem that any manufacturer could do whatever the hell they wanted to do. Until Honeycomb, all Android tablets used ugly (fragile) hacks to scale up phone interfaces. From Google's own admission, they did the same for Honeycomb, and won't be releasing the source because of it. Hopefully, they will eventually get it right.
