So just thinking out loud here: I love my iPad. Love the portability and the battery life. And I have no doubt that as technology continues to advance, we'll see these things inching closer and closer to full laptop replacements. What role do you see tablets playing in our daily lives, say, 5-6 years down the road? I ask because smartphones will make similar technological advances and are inherently more portable than tablets. Laptops will also continue to get thinner and more power efficient (and, at least for the foreseeable future, a physical keyboard is still the most efficient input method we have). So will tablets be relegated primarily to the realm of luxury device / couch internet browser? Or will they see mass adoption and be a permanent fixture in meetings, classrooms, etc. of the future? Interested to hear your thoughts!
