Sony's PSP Go might be the red-headed stepchild of handheld consoles. The reason we say that is because Sony just permanently slashed $50 off the price of the PSP Go, which now carries an MSRP of $150, but the console maker did so without making a peep. No fanfare, no ballyhooing, not even a curt press release. That's in stark contrast to Sony championing a new lower price for the regular PSP console just one week ago, news of which was announced on Sony's official PlayStation blog and various marketing materials.
