With Google's Nexus 7 shipping to those who pre-ordered already, the rivalry between the new tablet and Amazon's Kindle Fire has been heating up.

Pressure for Amazon to come out with a better tablet is on.

The Nexus 7 has a 7-inch screen. According to Jobs & Hire, the device has powerful hardware and a useful design that will enhance the customer experience. It's a very convenient size considering its dimensions, and it provides the same features as bigger tablets bringing the web, email, games, and social media feeds to users' fingertips. The device also brings to life a 1280x 800 IPS touchscreen, comparable to the third generation iPad. It will come with Wi-Fi connection, Bluetooth, a camera, and GPS, and be thinner and lighter.

In comparison with the Kindle Fire, both tablets work only with a Wi-Fi connection, and the screens are the same size. Both sell for $199. However, the Nexus 7 has a resolution of 1280 x 800 pixels, while the Kindle Fire's has 1024 x 600, according to Bloomberg.

The Nexus 7 is also thinner and 18% lighter. It also has a camera and Bluetooth, both which the Kindle Fire doesn't have. The new tablet also has a GPS.

The Nexus 7 also has great software performance. According to Jobs & Hire, Amazon's Kindle Fire and Barnes & Noble's Nook tablet are known for facing slow animations and screens, while Nexus 7 does not have those problems. It is the first quad-core 7-inch tablet, which smoothly and clearly loads magazines, books, music, websites, and apps with no problem.

Newsday said, "For buyers of Amazon's Kindle Fire, we now have the answer: You should have waited."

According to SFGate, early buyers will get a $25 credit in the Play store, making the $199 price that much more attractive.

Some say that the Kindle Fire still does its justice.

"There is something exciting about Kindle Fire too and this is where it beats Nexus 7 - it is the Amazon app-store for e-books, music, movies and videos that are loaded enough to keep a user happy and busy for a lifetime. And yes, Kindle Fire does boast of an excellent HTML5 browser (Amazon Silk)," a report from Mobile & Apps said.

Also, some say the Nexus 7 is not all that great like everyone is making it out to be. "You can't add shortcuts and widgets by pressing on one of the five home screens -- that will only get you an option to change the wallpaper," Wired.co.uk said. "And when you turn it on its side, it won't automatically switch to landscape mode when you're on one of the five home screens."

The Nexus 7 runs on Jelly Bean, the latest version of Google's Android software (Android 4.1).

Reports say that the Kindle Fire recently acquired the Android 4.1 Jelly Bean port.

According to ZDNet, earlier last week Google open-sourced Jelly Bean for third-party modification. Now, Kindle Fire owners can install Jelly Bean on their tablet.

Over on XDA Developers, forum user "Hashcode" revealed that he has ported Google's latest mobile OS to the device, ZDNet reported.

Even though it looks like they are working together in this instance, the competition is not over.

Reports said that Amazon is coming out with Kindle Fire 2, which will be thinner and lighter than the original. The new Kindle will be fit to display a 1280 x 800 pixel resolution, which will make it sharper and more vibrant. No one knows the price as of now. This tablet is expected to release on August 7 of this year, reports said.
