Though major retailers haven't yet updated their listings to reflect the new price, Sony Computer Entertainment America has updated its official PSP site to read, "Now you can enjoy the sleek, totally-digital PSP Go system for $149.99 MSRP and the unsurpassed PSP-3000 system for $129.99 MSRP."

Since the PSP's debut in late 2004, the handheld has gone on to move 67.8 million units around the world, 23 million of which were sold in North America.

Cool, maybe we can see PSP > 50k someday again!

Well this should help sells I would think.

What about Europe, Sony?

So does that make psp go most cost effective mp3/avi player? :)

It was already pretty unnexpensive in this regard but now it might really be the most cost effective.

How much does a good memory card for it cost though? I would need at least 16GB to make it worthwhile to replace my iPod Touch. 

It already has 16 GB built in.

You can upgrade that to 32 with MS card.

newegg says 45$ :

Oh nice that's not bad at all! Thanks.

It already has 16 GB built in, but the card suggested isnt the right type of card for the PSPgo. You need a M2 (memory stick micro). I think 8 GB is currently the maximum you can purchase:
