More than two years after their debut, Wiis are still tough to find in stores. In that time, Nintendo has released just enough great games (and nongames like Wii Fit) to tease gamers. Nintendo continues to develop new peripherals like the WiiSpeak speakerphone attachment (coming this fall), but the company says that only a handful of marquee titles will appear by the end of 2008.
In contrast, Sony's PlayStation Portable continues to gain unique titles and cool features--if you have a Wi-Fi connection (having a PlayStation 3 doesn't hurt either). Now in its second generation, the PSP offers Skype, Internet radio, the ability to upload movies from a PS3 directly to your handheld, and downloadable translation travel packs. Plus, you can play games remotely and view content stored on your PlayStation 3 over a Wi-Fi network.
