I'm not talking about PSP Minis or small games like Street Fighter Alpha 3 Max, or even comic books. You mean a full fledged PSP game that is in the range of 1GB or more can down load in 5 minutes? Even my PC and my hard wired PS3/360 can't download data that fast!! If this wireless-N (that I admit I've never heard of) can download data that fast then I'm gonna give Sony the benefit of the doubt. The market is crowding fast and there are still those intimidated by digital media, but I'll be onboard. Is the mass market ready, though? |
Yes the market has been ready for about 3 years now. And max speed Wireless-N is capable of is 150mbps over a distance of about 200 meters.
And when i state that the standard has been around for 3 years. Before N, there was N-Draft, which was a pre-release of the signal. It was out 3 years before N was standardized.
