Google Nexus One
Partnered with HTC, the Nexus One based itself on the Desire - the very first phone to win our coveted 5 star review. It had some competition at the time, having to win over fans from the likes of Symbian, BlackBerry, and those that had fallen in love with the iPhone 3GS.
$529 (around £330) bought you a single-core 1GHz processor, backed with 512MB RAM and 4GB of storage (and a microSD slot believe it or not). It also packed, what is considered small by today's standards, a 3.7-inch 480x800 screen to show off Android 2.1 Eclair.
A 5MP camera sat on the back, giving the Nexus One a lot to shout about given that the 3GS came with 3.2MP. To keep things running was a 1400mAh battery, which gave the Nexus One up to 7 hours 3G talk time.

Google Nexus S
Things had changed by the time the second iteration of Google's smartphone, the Nexus S, launched less than a year later at just over £400.
Google moved to partner with Samsung to launch Android 2.3 Gingerbread. Google needed its impressive weaponry to fight it out with the iPhone 4, the biggest competitor to the Nexus S at the time.
The Nexus S based itself heavily on the Samsung Galaxy S, although coming similarly specced to the Nexus One. A single-core 1GHz processor, 512MB RAM, 5MP camera all seems familiar, but storage was given a boost to 16GB, but no microSD slot.
The screen was also improved (although the 480 x 800 resolution was stretched to 4 inches), with Samsung's Super AMOLED technology in use. The battery was also boosted, to 1500mAh for a similar talk time. NFC also made its first Nexus appearance here.

Samsung Galaxy Nexus
By the time the Galaxy Nexus had launched, another phone had garnered our 5 star review, the Samsung Galaxy S2. At £429, it aimed to challenge the iPhone 4S, a phone that was making waves as it improved greatly on the iPhone 4.
Paired with Samsung again, Google looked to get some of the S2 magic into the Galaxy Nexus. This meant a 1.2GHz dual-core processor, 1GB RAM and 16GB storage. The camera took a boost, but was still measured at 5MP, and the battery was now 1750mAh.
As with all Nexus launches, the Galaxy Nexus heralded Android 4.0 Ice Cream Sandwich, displayed proudly on a 4.65-inch 720x1280 Super AMOLED display.

Google Nexus 4
Google decided to move across South Korea for its next Nexus iteration, with LG taking up the reins for the Google Nexus 4 handset. Things were looking a little more difficult for LG, with the market now populated with the iPhone 5, Samsung Galaxy S3 and HTC One X.
LG were desperate to get back into the smartphone making market, so its partnership with Google seemed ideal, giving birth to a device sporting a 768x1280 4.7-inch screen, 1.5GHz quad-core processor, 2GB RAM, 8 or 16GB storage and an 8MP camera.
It launched with Android 4.2 Jelly Bean, and a 2100mAh battery, giving it 15 hours of 3G talk time. Perhaps the biggest game changer was the £269 price tag, that unfortunately has yet to revolutionise the mobile market pricing in the way we might have hoped.

Google Nexus 5
The Google Nexus 5 is the new kid on the Nexus block and from initial impressions it's comfortably the best Nexus smartphone to date, although we'll reserve proper judgement until our in-depth review.
Again, LG is the partner of choice and the Nexus 5 welcomes the arrival of Android 4.4 KitKat and a similarly cheap launch price a la Nexus 4, if not a shade more expensive.
With a beefed up 2.26GHz quad-core processor, 2GB of RAM and a 4.95-inch screen full HD display the Nexus 5 is taking on the likes of the HTC One, Samsung Galaxy S4, iPhone 5S and LG's own G2 - but at a price point which makes it supremely attractive.
