The Google Nexus 7 has been the biggest tablet release of the year. This product sports Android 4.1 JellyBean, a quad core processor, 12 graphics cores, scratch resistant glass all for $250 or less. So, there is no wonder why all of those who pre-ordered cannot take the wait any longer.
The aspect of the pre-order that seems to anger those who participated are that eager buyers went directly into Sam’s Club and came out with a device the same day. I actually ordered my device on the day it was announced during Google I/O (along with millions more) and yet I am still patiently waiting the arrival of my Nexus 7.
Bottom line: Some are mad — however, there is nothing that we can do except wait for our beautiful game-changing 7 inch tablets to arrive at our doorstep. In addition, calling the Play Store 1(855)836-3987 will lead you to a message informing that pre-orders are indeed shipping. Realize that once you have this device in your hands, all of the turmoil will instantly leave.

As someone trying to set up a “fan site” I was kinda hoping to be one of the first to get one, but that aside, I totally agree. When I look back at things I’ve had to wait for in the past the additional wait might have seemed annoying at the time but a week later, a month later, a year later it doesn’t make the slightest bit of difference. Besides, I won’t get a good chance to play with it until the weekend so it doesn’t really matter – but I do hope it arrives by then…!
