Kevin C. Tofel at GigaOM investigates the tricky problem of counting Android tablets:
Next is the question of “what is an Android tablet?” It sounds like a simple question to answer, but it’s not.
Three sizable groups are being included in this count that are questionable:
- Tablets that haven’t been sold to customers yet.
- Tablets running Android 2.x.
- The Nook Color, which can only run most Android apps if it’s hacked.
What “counts” as an Android device is only going to get more vague over time as more “Android under the hood” devices, like the Nook Color and Kindle Fire, blur the lines.
