Gadgets: Analyze your golf swing with simulator Optishot2

Remember the old putting games with the electronic "hole" that shot your golf ball back to you? Optishot2 is a revved-up, modern version of that. It is a golf simulator that connects to a Mac or Windows computer. It isn't a video game. Instead of a game controller, you use your clubs to hit real (or, more likely, foam if you're indoors) golf balls off an artificial turf mat with embedded infrared sensors that analyze your swing. You'll need an 8 ½-foot ceiling. Virtual play is on some of the world's finest courses, or a driving range if you prefer. For more information, go to optishotgolf.com.

After returning in force to its keyboard roots last year, BlackBerry jumped back into touch-screen phones last week at the Mobile World Congress, announcing the 5-inch BlackBerry Leap. The phone, which will have a 25-hour battery life, goes on sale in Europe in April. There is no word on whether it will be sold in the United States.

Its specifications are appropriately middle of the road: a high but not extremely high-definition screen, an eight megapixel rear-facing camera and a two megapixel front-facing camera, acceptable processor and memory specs, and a slightly heavy weight compared with some of the competition.

Handle links three productivity apps into one — the e-mail inbox, calendar and to-do list — to help you get a grip on your life. Handle makes it easy to create to-dos and calendar events from e-mails in your inbox, and can show you everything on one screen. When dealing with e-mails, users simply have to swipe left or right on the message to create a reminder or event, choose to read a certain e-mail later or delete it. To take advantage of the features, you will have to give the app access to your calendars and inboxes. One big caveat? The app works with Gmail addresses only, so if your company or personal e-mail is on another service, you're out of luck.
