PlayStation Vita（PS Vita）是繼PlayStation Portable（PSP）之後由索尼互動娛樂開發及發行的掌上遊戲機。於2011年12月17日在日本首發，隨後於2012年初在北美、歐洲及其他地區推出。

目標是超越PSP的功能，提供玩家們更強大的性能和豐富的遊玩體驗。主機配有5英寸的多點觸控電容屏幕，分辨率為960×544像素，顯示效果非常出色。重量約為219G，對於經常外出遊玩的玩家來說，這是一個理想的選擇。

此外還搭載ARM Cortex-A9 MPCore四核心處理器，配有SGX543MP4+圖形處理器。主機內建512MB RAM和128MB VRAM，存儲空間為32GB，並且支持microSD卡擴展存儲。

PS Vita在日本的售價為$9,954日元，首發的首兩天內銷售量超過30萬台，表現相當強勁。然而，隨著時間的推移，銷售熱度逐漸減弱。到其生命周期結束時，

PS Vita全球銷量約為1600萬台，相較於其前身PSP超過8000萬台的銷量，顯得相對遜色 (註:索尼在2012年3月31日有公布PS系列的所有銷售數據，唯獨沒有揭露PS Vita)。

主機的優點在其高品質的OLED屏幕，在顯示上效果非常出色，雙模擬搖桿提供接近家用主機的操作體驗。還支持播放PSP和PS1的數位遊戲。Remote Play功能讓玩家在PS Vita上串流和遊玩PlayStation 4的遊戲。該平台也受到許多獨立遊戲開發者的歡迎，帶來許多獨特且有趣的遊戲作品。

然而，缺點是專屬的記憶卡，價格相當昂貴，讓不少玩家望而卻步。其次，索尼在推出後不久便逐漸減少對PS Vita的遊戲開發支持，使得遊戲陣容未能持續壯大。再者，其電池續航時間有限，一般僅能持續3到5小時。最後，面對手機遊戲的激烈競爭，市場表現受到一定影響。

在PS Vita平台上，推出的遊戲超過560款，取得不錯銷量和口碑的有《秘境探險：黃金深淵》，能凸顯PS Vita圖形性能的冒險遊戲、《女神異聞錄4 黃金版》則被廣泛認為是該平台上最好的角色扮演遊戲。其他受歡迎的作品還包括《重力異想世界》（GRAVITY DAZE/重力的眩暈）、《撕紙小郵差》和《殺戮地帶：傭兵》。

總結來說，這款強大的掌上遊戲機，儘管面臨一些挑戰和限制，但其輕便耐用的設計和豐富的遊戲內容仍使其成為玩家心目中的佳作。無論是尋求挑戰體驗，還是追求獨特刺激作品的愛好者，都能在PS Vita中找到樂趣。

PlayStation Vita (PS Vita) is a handheld gaming console developed and released by Sony Interactive Entertainment, following the PlayStation Portable (PSP). It was first launched in Japan on December 17, 2011, and subsequently released in North America, Europe, and other regions in early 2012.

The PS Vita aimed to surpass the capabilities of the PSP, offering players more powerful performance and a richer gaming experience. The console features a 5-inch multi-touch capacitive screen with a resolution of 960×544 pixels, providing excellent display quality. Weighing approximately 219 grams, it is an ideal choice for players who frequently game on the go.

Additionally, the PS Vita is equipped with an ARM Cortex-A9 MPCore quad-core processor and an SGX543MP4+ graphics processor. The console includes 512MB of RAM and 128MB of VRAM, with a storage capacity of 32GB, supporting microSD card expansion.

In Japan, the PS Vita was priced at ¥9,954 yen, with over 300,000 units sold within the first two days of its release, showcasing strong initial performance. However, over time, sales momentum slowed. By the end of its lifecycle, the PS Vita had sold approximately 16 million units worldwide, which was relatively modest compared to its predecessor, the PSP, which sold over 80 million units (note: Sony disclosed sales data for all PS series up to March 31, 2012, but did not reveal specific figures for the PS Vita).

The PS Vita's strengths include its high-quality OLED screen, which delivers outstanding display performance, and dual analog sticks that offer a gaming experience similar to home consoles. It also supports playing digital games from the PSP and PS1 libraries. The Remote Play feature allows players to stream and play PlayStation 4 games on the PS Vita. The platform has also been popular with many independent game developers, bringing a variety of unique and engaging titles to the console.

However, there are some drawbacks. The proprietary memory cards are relatively expensive, deterring some players. Additionally, Sony gradually reduced its support for game development on the PS Vita shortly after its release, preventing the game library from growing significantly. Furthermore, the battery life is limited, typically lasting only 3 to 5 hours. Lastly, the intense competition from mobile gaming also impacted its market performance.

On the PS Vita platform, more than 560 games were released. Some of the well-received and best-selling titles include "Uncharted: Golden Abyss," which showcased the PS Vita's graphical capabilities in an adventure game format, and "Persona 4 Golden," widely regarded as one of the best role-playing games on the platform. Other popular titles include "Gravity Rush," "Tearaway," and "Killzone: Mercenary."

In conclusion, despite facing some challenges and limitations, the PS Vita remains a powerful handheld gaming console. Its portable and durable design, coupled with a rich array of game content, has made it a cherished device among players. Whether seeking challenging experiences or unique and exciting titles, gamers can find enjoyment in the PS Vita.
