PSP3000 VS PSP2000
Screen
The biggest improvement of PSP 3000 is the obvious changes of LCD brilliance,which can be seen from the following picture, since the colour gamut of the new LCD panel is twice as long as the former one and the reaction time is twice while the contrast gradient is quintupling. The new LCD panel adopts the latest anti-reflection tehcnique, which makes PSP 3000 useable under strong sunshine.
Micphone
A big alteration to the hardware of PSP 3000 comes from the newly built-in Micphone. Currently PSP system builds in two online chat tools, skype and Go!Message. Both of them can be used relying on the perpheral of micphone in the old version. Although Sony had launched a Micphone bundling with TakeMan, it was not popularized for no portability. For the moment the new version resolves this problem and makes players enjoy Skype in any place and time.
Video Output
The PSP 2000(old version)only support successive scaned TV linked by chromatic aberration and terminal D. But the PSP 3000(new version) support not only successive scans TV,but also interlaced scanning TV, which reduces the requirements of PSP external video to TV. This is a very important function to those who have high requirements on the extended function of PSP 3000.
Cross Head Key
The operation handfeel of PSP is always doubted by players, but this time the improvement will offer the cross head key better operation feel.
Steel Ring
The steel ring of PSP 3000 is more thin and avoid scratch. This is the best embodiment of Sony willingly learning from opinions from all sides.
Set Key
The logo in PSP 2000 is Playstation, but PSP 3000 is the mark of Sony. However, Sony never abandons the long-time developed playstation. So it changes the Home key to PS key and meanwhile change the shape. All PS3 players should know that PS3 achieved to turn on XMB when playing through software upgrade. That moment will not be far from now for PSP.
