People who ordered the Google Glass at the Google I/O in 2012 will get their pair in a few days. Glass Explorers, which manufactures the device, said on Monday that the first batch of glasses just came off the production line and will be immediately shipped.

There were 2,500 orders of the Google Glass at the I/O developer conference in San Francisco. Google started to notify via email those who ordered the glasses to expect the delivery of their pair soon.

So far, 2,000 pairs had just come off the production line in two and a half days.

"We know you've been standing by patiently to get Glass. So, instead of waiting for all the devices to be ready, we want to start delivering them to you now. We're producing enough for everyone, but only a portion of them are ready today. There, we'll be notifying you in waves, and as soon as we're ready to invite you, we'll let you know. When the time comes, you'll receive an email with all the details," TechCrunch quoted the letter from the Glass Team.

However, not everyone is happy with the growing popularity of Google Glass. In an article at PCMag, John Dvorak cited several reasons for not liking the device, including it being creepy, an unnecessary technology and its role in isolating users from the rest of society.

He compared the device to the iPod which young people also lapped up when it was released.

"People began shutting out society when the iPod became mainstream. There you were gyrating or singing to yourself in your own little world without any concern for anything going in around you - like the little kid who plugs his ears and hums so he cannot not heart whatever it is that mom is telling him," he wrote.

He pointed out that devices, including laptops and tablets, are the reason why a presenter to a tech audience would be lucky to have 10 per cent of the group listening to the speaker. "They either get sidetracked by a point and go dig deeper on Wikipedia, or they tweet and end up in a consuming Twitter conversation," he added.

He warned, "Google Glass is the next step toward complete isolation. I can only imagine people looking up like robots, appearing to be paying attention while doing who-know-what with the gadget."

CNET, however, believes there are top 5 potential uses for Google Glass in this list by Donald Bell.
