The market for Android tablet pcs has been flooded with inexpensive generic Android tablets from China and India that typically provide scaled-down hardware features - no GPS or 3G/wireless carrier antennae - and instead focus on the essentials - Wifi, touchscreen, speakers and media jacks - with a priority on hitting as low a price-point as possible.
While some very impressive Android tablets have come off these OEM production lines, with full 10" monitors, 1GHz CPU, USB2.0 ports, and many with Android 2.1 or better, even the best Android tablets from these overseas manufacturers seem to suffer from two primary complaints among consumers:
1. Lack of the Android Marketplace app
2. Resistive touch screens instead of more sensitive "Capacitive" touch screens
Google's Android Marketplace Issue:
It would appear for the time being that the issue with getting approved by Google to pre-install the Android Marketplace app onto any of these Android tablet devices will not be resolved anytime soon. Much of this has to do with Google's position that the current versions of Android (currently 2.2, aka - "Froyo") do not support the tablet "form factor", and even their hardware compliance documentation specifies a screen size no MORE than 5.8" measured diagonally - which would theoretically disqualify all tablets of any usable size from receiving the license to pre-install the market app, though Google has shown that it is willing to grant exemptions on certain hardware items, at least to its friends in the Open Handset Alliance.
Google's hardware requirements for licensing the Marketplace app also dictatet that compliant devices must have among other required hardware; mobile carrier antannae, GPS, rear-facing cameras, accelerometer, Bluetooth, and a long list of hardware requirements that are not necessarily essential for creating an effective tablet with Android, and certainly not conducive to achieving the lowest price point possible.
Of course, customers don't NEED to have the Android Marketplace app installed on their Android tablets in order to install games and apps onto their devices - they can still do this by simply downloading apps off the internet using a PC computer and saving these files onto an SD card. Then they swap the SD card to their tablet and can launch the apps from the SD card to their Android tablet from there, so some part of the Android Marketplace app appeal is simply convenience.
It would appear that many of these items will be resolved with future releases of Android - "Gingerbread" is supposedly designed to better support tablets and Google and their allies will certainly be targeting the tablet market in 2011 in hopes of chipping away at iPad's marketshare. Whether they try to make it easy for smaller factories to get in on the game seems a bit unlikely, though in the meantime it seems there is little alternative in the market for any affordable tablets with the market app.
The Touch Screen Issue: Resistive vs. Capacitive
The other galring issue with nearly all of the Android tablets to come out of China is the use of a resistive touch screen rather than the current industry standard capacitive screens. Resistive screens work by sensing the pressure applied to the surface of the screen, whereas capacitive screens work by sensing the current in your finger or specialized stylus. While resisitve screens provide the benefits of low cost and can be used with any stylus or even a gloved finger, capacitive screens have proven to be far more responsive and have all but rendered resistive screens obsolete in the smartphone market.
The only real issue here is cost and the cultural misperseption among China's factory managers that the lowest price will ultimately win. Considering that larger resistive screens add as little as $10-20 to the manufacturing cost of these devices, the added value should be obvious to any consumer minded product development engineer. However, very few of these factory managers actually use these devices and those that do are accostomed to Chinese quality including pervasive use of resistive touch screens. So it has fallen on their Western partners and wholesale customers to direct and demand the development of these Android tablets with capacitive screens, and the first wave of these upgraded products is slated to hit the market in the next month if not sooner.
Still, the cost to retool machinery in the upgrade to capacitive screens will cause these manufacturers to initially charge a premium for these capacitive screen devices, and this will inevitiably be passed on to end consumers, but it will only be a matter of time befor capacitive screens are the defacto feature set for all Android tablets save for special circumstances or for those chasing the absolute basement price-point.
Conclusion:
Since one arguably does not need the Android Marketplace apps to get apps onto their Android tablet devices, this point could be seen as insignificant, however ease-of-use has been proven to be a significant factor in iPad's success and for less sophisticated users the routine of transfering apps to a tablet via a SD card or USB stick may be confusing. On the other-hand, resistive touch screens seem to be generally on their way out anyway, though the impact a capacitive screen upgrade will have on costs may keep resistives in the market, and anyone who has used a resistive touch-screen tablet can tell you that it can be quite frustrating at times, though a stylus can help quite significantly.
I would suggest that if you had to choose one or the other, get the capacitive screen and don't worry about the Android Market app - you'll ultimately save yourself a lot of money if you can learn to "borrow" these apps off the internet by downloading them off file hosting sites or via torretz and other file sharing systems.
