Google LG Nexus 5 smartphone with Android 4.4 aka KitKat

LG Nexus 5 with Android 4.4 KitKat

Very soon Google will present to public LG Nexus 5 - smartphone that will replace Nexus 4 (prices on Nexus 4 were lowered last month in Google Play Store: 8GB $199 and 16GB $249). Phone was already leaked and revealed: one of the developers "left" it in the bar for public to drool over it. Just a few days ago LG Nexus 5 specs were also "leaked" to keep geeks and smartphones/android fans discussing it on multiple forums and social networks. This type of advertising (through leaks) seems to be the last expensive and the most effective to target right audience. If you want to know specs, it will be listed below with explanations of terms for a regular user like most of us.
So, it's expected to be available Nexus 5 with 16GB, 32GB and possibly 64GB internal storage (in simple language, it's like non-removable computer hard drive). It will also will come with different battery capacity.

Prices: 
1. Nexus 5 with 16GB internal memory and 2,300 mAh battery will cost $299 (USD). 
2. Nexus 5 with 32GB intermal memory and 3,000 mAh battery will cost $399 (USD). 
3. If 64GB version will be available, it may have also 3,000 mAh battery, but price is unknown. Probably, $499 or $549.
Speaking of battery capacity. The mAh capacity rating refers to the storage capacity available. A battery with a capacity rating of 2,300 mAh could deliver a current of 2,300mA for one hour. Higher mAh ratings for the battery type will last longer. 3000mAhcapacity is similar to LG G2 phone and is one of the most powerful phone with long lasting battery.
Other specs: Nexus 5 will be equipped with 5-inch full HD display, a 2.3GHz Snapdragon 800 chipset, 2GB of RAM, an 8-megapixel rear camera with optical image stabilization (OIS), a 1.3-megapixel front-facing camera. 
Camera: 8-megapixel (8MP) camera is more than enough for daily usage to shoot food for instagram or kids parties. Some people even decreasing MPs to 5MP and quality of images is still great unless you are planning to print 8x11" photos or posters. For large prints, use 8-megapixel option in camera. Remember, lower number of megapixels will make smaller size images and it will be easier to email them or text to your friends. But you may experiment with camera  in order to find your ideal options.

Good: Price, speed, ease to use (specially if you have Nexus 4 or familiar with Android smartphones). KitKat or Android 4.4 (it is expected to be efficient that even smaller capacity battery will last longer). Google phones get updates first (may have bugs, but they fix them quick).
Bad: 1. 2,300mAh non-removable battery and no option for microSD removable card may disappoint some users. It's not bad at all. HTC, Apple and other manufacturers of hardware for smartphones also chose way of build-in battery and memory. Samsung is the one that has replaceable battery (in case if there is a problem with the battery, you do not have to go to customer service and replace phone. Just change your battery. Some people claim that they carry around second charged battery and use it when no access to charger. For this purpose you may use tiny portable solar charger for $10). 2. Expandable memory (slot for miroSD card). Google phones get updates first (may have bugs, but they fix them quick).


What else is not covered here? Please, correct me or ask questions about this phone. My personal preference is Nexus 5 version with 32GB 3,000mAh battery for $399.
