I didn't know that there was something similar for the Sony Playstation Portable (PSP), but minus the magnets. Turns out to be that the Display Stand Portable (available in Black and White) is also manufactured by Hori. It supports both the original PSP (PSP-1000) and the new PSP Slim & Lite (PSP-2000).
Have something like a silicon skin or armour protecting your new Slim & Lite? No problem as the display stand will take on all comers as it will accomodate the extra protection in its PSP-1000 mode.
The Hori Display Stand Portable is currently available at Play-Asia in two colours, black and white, at a discounted price of USD 4.99. Click here for further details.
The Nintendo DS Magnet Stand is also available at Play-Asia, for a price of USD 14.90. Click here for further details.
