More details about PSP GO

As I have mentioned in the last post, SONY next generation PSP "PSP GO" has been leaked. Here is some more details about it, let's check them out.
Form factor: 3.8-inch wide screen (previous PSP models are 4.3-inch). 
                      43 percent lighter than the PSP 3000.
                      Slides the screen up to reveal the controls.
Storage: 16GB of built-in flash memory, expandable via a Memory Stick Micro slot.
                No UMD (Universal Media Disc) drive on the PSP Go.
Controls: A 4-way d-pad on the left, circle, square, cross, triangle buttons on the right, select/start buttons in the center, and the PlayStation "home" button to the left of the screen.
                The analog control places closer to the center of the control deck rather than the outside right, where it sits on earlier PSPs.
Wireless: Wi-Fi support
                 Bluetooth (supports both Bluetooth headsets and Bluetooth-enabled cell phone) 
Games:  Sony would like to see the PSP platform become home to shorter, simpler "pick up and play" games that can be downloaded from the PlayStation Store on a whim. 
Digital media support: Presumably, PSP Go will have at least the same baseline media features as the existing PSP models, which includes ample support for music, video, and photo files. So, we still have to face the problem that we need to convert video and audio files to the formats PSP GO support, video convert software will be needed again.
PS3 integration: Again, it appears that the existing interoperability between the PS3 and the PSP line will be carried over to the PSP Go. That includes the ability to cross-load some games and media, as well as the Remote Play option (access PS3-based content from the PSP over the Internet).
Price and availability: Not specified.
Summary: Without a UMD drive, there is no doubt that the existing UMD games will not be available for PSP GO (Dear god......I have about 200 UMD games, what shoud I do with them?). The good news is that a wide selection of UMD games already exists on the Playstation store for the existing PSP owners, and recenetly games are download-only, Patapon2 for example. 
                  Since PSP Go supports Bluetooth-enbled cell phone, it is reasonable to presum that when Wi-Fi is not available, it is possible to browsing Internet via cell phone with 3G data connection.
