MXNA on PSP As MXNA has become a very popular aggregator, I often like to check it out in not-so-popular browsers. The Playstation Portable 2.0 firmware (currently available in Japan and due any time now in the US) includes a reasonably full-featured web browser – and although the English release date for the firmware has slipped a bit, I wanted to confirm that MXNA looks feels and acts just as you'd expect on the PSP (Japanese v2.0 firmware used here).
