PSP - PlayStationPortable

         On October 17, 2004, Sony announced that the PSP would launch in Japan on December 12, 2004, at a price of $181 in 2004 for the base model and $226 for the Value System. The console's launch was a success with over 200,000 units sold the first day. Different color variations were also sold in bundle packs, which cost more than usual, around $200. Sony announced on February 3, 2005, that the PSP would go on sale in North America on March 24, 2005, in one configuration for a MSRP of $249. Some expressed concern over the high price, which was almost $20 higher than the system's price in Japan and more than $100 higher than the recently launched NintendoDS. Despite the concerns, the PSP's North American launch was a success, although reports two weeks later indicated that the system was not selling as well as expected despite Sony's claim that 500,000 units had been sold in the first two days. The console's PAL region launch was a resounding success, selling more than 185,000 units in the UK alone, selling out of all stock nationwide in the UK within three hours of launch, more than doubling the previous first-day sales record of 87,000 units set by the Nintendo DS. The system also enjoyed great success in other areas of the PAL region with more than 25,000 units preordered in Australia and nearly one million units sold across Europe in the first week.

Redesigns

 PSP-2000

PSP-2000

The PSP-2000 (marketed in PAL areas as "PSP Slim & Lite" and still marketed as PSP in North America, Japan, China, India, Italy, and Portugal) is the first redesign of the PlayStation Portable.
At E3 2007, Sony released information about a slimmer and lighter version of the PlayStation Portable. The new PSP was announced to be 33% lighter and 19% slimmer than the original PSP system. The model numbers were changed to PSP-2000, following the previous region-based numbering scheme (cf. the PSP-1000 numbering scheme of the "old" PSP model).
It was released on August 30, 2007, in Hong Kong, on September 5, 2007, in Europe, on September 6, 2007, in North America, September 7, 2007, in South Korea and September 12, 2007, in Australia. On January 8, 2008, built-in Skype Wi-Fi Internet phone service was added via firmware updates.

PSP-3000

In comparison to the PSP-2000, the PSP-3000 (marketed in PAL areas as "PSP Slim & Lite (with enhanced screen + built in microphone)" and still marketed as PSP in North America and Japan) has an improved LCD screen featuring an increased color range, five times the contrast ratio, half the pixel response time to reduce ghosting and blurring effects, new sub-pixel structure, and anti-reflective technology to improve outdoor playability. The disc tray, logos, and buttons have all been redesigned and the system now has a microphone. In addition, all games may now be output by component or composite using the video out cable.
In its first four days on sale, the PSP-3000 sold 141,270 units in Japan, according to Famitsu. In October 2008, the PSP-3000 sold 267,000 units in Japan, according to Enterbrain.

PSP-E1000

PSP-E1000

Announced at Gamescom 2011, the PSP-E1000 is a budget-focused model of the PSP which will be available across the PAL region for an RRP of €99.99. Unlike previous PSP models, the E1000 does not feature Wi-fi capabilities and has a matte "charcoal black" finish similar to the slim PlayStation 3. Also, it will only feature a mono speaker instead of the previous models' stereo speakers.

Hardware

The PSP Slim & Lite system is 19% thinner and 33% lighter than the original PSP system (reduced from 23 mm to 18.6 mm and from 280 grams [9.87 ounces] to 189 grams [6.66 ounces]). Internal changes to achieve this include the removal of a metal chassis (used to reduce damage in the event of sudden trauma to the system resulting from the user dropping the system on a hard surface). However, users have complained about generally poor hardware assembly like misaligned faceplates and loose/creaky battery covers.
Other changes include improved WLAN modules and Micro-controller, and a thinner and much brighter LCD. To cater for the original PSP generation's poor load times of UMD games,the internal memory (RAM and Flash ROM) was doubled from 32 MB to 64 MB with a part of it now acting as a cache, which also improved the web browser's performance.
