However, unlike Sony's home consoles such as the Play Station 3 and the Play Station 4, it is not possible to play Blu-ray or DVD movies on the Play Station Portable directly since it lacks of a standard Blu-ray or DVD drive.
While it does have a UMD drive and there exist UMD movies, the UMD format never saw implementation on any device other than the Play Station Portable and as a result the market is very limited compared to those for other optical media formats.The browser also has limited tabbed browsing, with a maximum of three tabs.When a website tries to open a link in a new window, the browser opens it in a new tab.The current version of the software, 6.61, was made available on January 15, 2015.It is a minor update released more than three years after the release of the previous version 6.60 in 2011.The Play Station Portable uses the Xross Media Bar (XMB) as its graphical user interface, which is also used in the Play Station 3 (PS3) console, a variety of Sony BRAVIA HDTVs, Blu-ray disc players and many more Sony products.
