7 tech combos we'd like to see

GadgetsNikon's Coolpix S1000pj digital camera with a built-in projector sounds as good as peanut butter and chocolate. Why didn't anyone think of this sooner? And If a point-and-shoot camera can double as a video projector, what other tech marriages are possible? Here are a few combinations we'd like to see.

1. Mobile phone and breathalyser. You've had a drink at a bar, and you feel sober enough to drive - but you may be legally impaired. Rather than risk it, you breathe into your mobile phone, which tells you if you're fit to get behind the wheel. In fact, South Korean manufacturer already sells one of these, but not in this country.

2. TiVo for your car radio. TiVo and other DVRs are great for recording TV shows and bypassing adverts. But how about TiVo for the car radio? You're driving to work and want to hear a radio show or interview that's coming up. But you don't have time. Wouldn't it be great to hit a record button on the radio and listen later? Skipping the annoying adverts for your local furniture sale would be nice too.

3. Universal remote with mini-TV display. This device would let you preview shows on your clicker before switching to them on your HDTV. The ultimate power for the person holding the remote! This makes TV picture-in-picture technology seem downright prehistoric.

4. GPS hiking device and flare gun. GPS devices for wilderness treks have satellite maps, and many smartphones now include Google Maps with satellite images. But what if you're injured, maybe stuck in a ravine without mobile service? A lot of good that GPS device will do you. That's when you pull out your GPS flare gun. Even better: a satellite-guided flare that automatically travels toward the closest populated area.

5. iPod and space heater. Why is Apple trying to extinguish claims that its iPods may overheat and burst into flames? Its approach is all wrong. Apple should embrace the iPod's toasty nature and market the device as a combo music player/space heater. Talk about savings.

6. Bluetooth earpiece and radar detector. So you're driving with a Bluetooth device stuck in your ear. Can't it do more than take calls? My suggestion: radar/laser detection to thwart The Fuzz. We'll worry about potential health complications later.

7. Inkjet printer with money-drain meter. How much ink are you wasting? What's the real cost of that £25 printer? With this combo device, you'll finally know for sure. (Latest printer reviews, tutorials and support.)
