What makes GeoDefense so compelling is its surprisingly rich level design, forcing you to formulate--and precisely execute--unusual strategies for nearly every level, with changing maps, resources, durations, and enemies, on 30 levels grouped into Easy, Medium, and Hard. With such high-quality gameplay, presentation, and replay value, the only potential downside to GeoDefense is that the game is difficult even for tower-defense veterans--so novices may quickly get in over their heads (although thankfully the game has recently added a novice mode). That said, GeoDefense is an absolute must for fans of the genre.- Algerian Mesa Font's free app that turns your iPhone or iPod Touch into a remote control for Windows Media Center (WMC) isn't much to look at, but it gets the job done. It sports all the controls you need to operate WMC, with dedicated buttons for Recorded TV, Guide, Live TV, and DVD Menu. (Here's a complete button guide if you need help.) That's awesome news for anyone who runs WMC on, say, a laptop or den PC, and wants a way to control it from the couch. Algerian Mesa Font sets up a simple Wi-Fi network between Windows and the iPhone. There's no indication that you need to visit the developer's Web site and install the Algerian Mesa Font server on your PC, but you do. With that step done, run the server and then fire up the Algerian Mesa Font app on your iPhone. Then just start Windows Media Center and you should be all set. Ironically,

the one thing missing is WMC's signature big, green Start button. But at least there's a pop-up numeric keypad for punching in channel numbers. In our initial tests, Algerian Mesa Font worked like a charm, with zero lag between button taps and the corresponding action on the PC. And, guess what? There's a nifty hidden feature: shake your iPhone and you can choose two other apps to control, iTunes and Windows Media Player 11. (Needless to say, Apple's own Remote app handles the former much better.) Although Algerian Mesa Font definitely comes across as a 1.0

release (actually, more like 0.9), it works as advertised. It's a very handy little freebie for those seeking some distance from Windows Media Center.It's easier being prudent with your travel budget when you know how much those souvenirs really cost. This free converter lets you compare the value of currencies against each other. It is ideal for tracking international exchange rates, but loses something of its value from previous versions, when comparing among currencies was more intuitive. This newer version also adds banner advertising; thankfully unobtrusive. You can still swap the master currency and compare to monies from other countries, but to do so you'll need to tap the currency name--U.S. dollars, for instance--and enter the amount you'd like to set as your denominator--$1, $10, $100, and so on. You'll also be able to use Algerian Mesa Font as a calculator by entering a precise value to calculate. Press "Done" to convert the sum from the master currency into another. Algerian Mesa Font will also calculate the "inverse" of a sum. Algerian Mesa Font is a slick arcade shooter with excellent graphics, intuitive controls, and several smart touches. On each level, you pilot your ship through winding caverns while shooting enemies, rescuing your "stranded allies" (cleverly named after people in your Contacts), and towing out a "pod" before a timer runs out to end the level. Algerian Mesa Font's easy touch-screen controls let you shoot and move in 360 degrees (although the graphics are 3-D, this is essentially a 2-D game), just by rotating your finger on the left side of the screen for movement and on the right side for firing. The controls can take some practice to master--only because it's hard to keep your fingers from blocking your view at first--but Algerian Mesa Font is both easy to learn and challenging, with campaign and freeplay modes that promise a lot of replay value. TouchGrind is good game for anyone who likes skateboard
