Windows: If you want to have voice chats over the Internet, Skype is probably your best choice. The latest version of this popular VoIP client, Skype 4.0 Beta, has a completely redesigned interface with more focus on video conference, along with other features to improve call quality, optimize contacts management and add more IM tools.
Mac: I still enjoy a game of Super Nes every once in a while, but instead of having to dig around for my console in a shoe box in some closet, I’ve installed ZSNES. This SNES emulator features a very comprehensive menu with all sorts of settings for buttons, sound and video among others. It can play back movies and browsing for ROMs on your Mac is really easy. Essential if you’re looking to play SNES or Super Famicom games on your Mac.
Smartphone: Battleships has come a long way since the days when you needed to scribble down grids on two pieces of paper, as Sea Battle proves. This well-presented mobile version of the popular military strategy game boasts impressive 3D graphics, cool music and sound effects, and even live speech commands. Sea Battle is also available for Pocket PC.
