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.
