In case you are not familiar with Square, Square is an application that allows anyone to accept payment cards using their mobile device. This is done with a tiny card reader that plugs into the headphone jack on the device. Unfortunately, Square is unavailable outside U.S. for the time being.

Square intends to bring immediacy, transparency, and approachability to the financial world. We want to enable all people to accept payments instantly, with access to all the information they need, in a way that feels amazing and engaging.  When you think about it, paying someone is just another form of communication, an exchange of value that deserves to have the same design and product considerations that every social service prides itself on maintaining.

Square is, in my opinion, a very interesting and innovative technology and I am really looking forward to see how this turns out. Have you tried Square? What do you think?

• Steve Jobs showed up saying they want to kick off 2010 by introducing a truly magical and revolutionary new product.
• There was a little talk about the success of the iPod and the iPhone over the last years with some historical and data reference. Plus, saying that Apple is a mobile devices company, that’s what we do.
• After wondering if there is room for a third category device in the middle of a laptop and/or a smartphone, Steve just said iPad.
• From that time and on it was all about applauding and embracing this new magical thing called the iPad.

We’ve always tried to be at the intersection of technology and liberal arts — we want to make the best tech, but have them be intuitive. It’s the combination of these two things that have let us make the iPad.

iPad’s main features inlcude:

• 9.7-inch LED-backlit glossy widescreen Multi-Touch display with IPS technology
• 1GHz Apple A4 custom-designed, high-performance, low-power system-on-a-chip
• Wi-Fi + 3G model
• 3.5-mm stereo headphone jack
• Built-in speakers
• Microphone

You may find out more about the iPad here. However, as you may have noticed, there a few missing features.

If you ask me, I was getting ready to catch up with the event along with gdgt’s and engadget’s live coverage. I was ready to listen to whatever Steve was ready to say. I mean, we were all ready for the best tablet pc ever, right? Well, the first impression of the iPad was like “hmmm.. it’s not bad”. Not that I don’t think this is an exceptional mobile device. Maybe I was overwhelmed by all the buzz going on about the Apple Tablet. I was waiting for something truly innovative and outstanding.

The User Interface was awesome, as usual in all Apple products. Could be better though. The whole idea of downloading the same apps you download for your iPhone was a bit surprising and also a good way to endorse the power of the iPhone App Store. Everything else seemed to be quite elegant.

Anyhow, Apple’s iPad has definitely killed the netbook market and we are about to witness, as I have said before, a change in personal computing in the years to come shifting the Personal Computer (P.C.) towards the mobile devices.
