Tactile Android buttons
The Android OS specifically calls out for at least three hardware navigation buttons: home, back, and menu (some also include a search button).
Like the Apple iPad, the Maylong M-150 included only one button on its face, relegating the other controls to touch-screen buttons. And though the Maylong’s one button looks like a Home button, it actually behaves like a back button. It’s bizarre and frustrating, and it does a disservice to the Android OS.
The lesson here: Android devices need the Android three-button hardware scheme to work properly. Also, test the buttons to make sure they behave as you’d expect.
Just because an Android device includes an app store doesn’t mean it uses the official Google app store. In fact, only a handful of Android tablets we’ve tested (Dell Streak, Samsung Galaxy Tab, ViewSonic ViewPad 7) actually include the Android Market.
Sometimes, an Android device will offer no app market at all (often the case for e-readers, such as the Nook Color). Others, such as the Maylong M-150 or Archos tablet line, use their own app store with limited offerings.
The easiest way to check if the app store is legit is to dive into the top-ranked apps and look at the selection. If you don’t see a Pandora, Gmail, Yelp, or other top-tier apps, you’re probably dealing with a phony storefront. Another way to tell, most phony storefronts only deal in free apps, or free demos that ask for money only after the app is installed.
You can get android tablets with 10 inch, 7 inch, or 5 inch screens, and they come with different level of on-board RAM, processing capabilities, and battery life. In my point of view, I think 7 inch model are fitting perfect for the hand. Compared to the iPad 9.7 inch screen, the only 7-inch screen, but still a great android alternative to the iPad. The display is a thin film transistor (TFT) LCD display at a resolution of 800*400. While iPad 9.7 inch model is heavier and bigger, I usually get my arm hurt when using for 2 more hours.
Now with more product flooding into the wholesale electronic stores, the competition upgrades. Choose right size for yourself base.
