The guys at DAP Review stumbled upon another no-name portable video play maker, neoSOL. Whether these devices actually exist or will ever appear for sale in the US is anyone's guess, but they have an interesting strategy.
neoSOL seems to be covering all the bases in terms of product design. The four devices listed on their website are basically the same under the hood, but each has slightly different form factor. Also the neoSOL players have pretty interesting specs: each only has a 2.5GB capacity, but a 2.2" OLED color screen, can record broadcast TV, plays and records MP3 and WMA audio and plays and records AVI, DivX, XVid and WMV video. That's a nice feature set but don't hold your breath for them to appear on the market.
