Can it be refueled from empty to full in 2 minutes like a gasoline engine? What is the battery lifespan? How much will they cost to be replaced?

Planning ahead is something thats needed no matter what you drive. No one embarks on a 300 mile roadtrip with the gas gauge blinking red. This one will have the "large LCD display" reminding you to recharge. The battery lifespan is usually in the excess of 100,000 miles, with typical NiMH batteries giving between 130,000-150,000 mile range. At this point, the batteries are expensive, but if you consider the amount of saving in fuel costs, oil changes, all sorts of filters and pumps, etc. over the course of 130k miles - you'd have saved up enough for a battery pack. Another interesting thing is that the cost of fossil based fuels is on the rise, whereas batteries are becoming less expensive over years.

The moral of the story is, if you can afford to spare $50K for starters, you can save quite a bit eventually.

Dual monitor support isn't really fragmentation. You can switch between single and dual screen, so devices with single screen will not be able to use all the dual-screen features available in Android. Same way having a slide-out qwerty keyboards in Android doesn't mean its fragmented, you just switch from on screen keyboard to a hardware keyboard.

+ - Plastic Memory Device Based On Electron Spins->

von_rick writes "From the article: "Our main achievement is that we applied this [vanadium tetracyanoethanide] polymer-based magnet semiconductor as a spin polarizer — meaning we could save data (spin up and down) on it using a tiny magnetic field — and a spin detector — meaning we could read the data back," Jung-Woo Yoo said.

A memory unit that is lighter and draws lower power levels would be a good replacement for conventional semiconductors. However, since the spins are controlled by application of magnetic fields, this technology would be susceptible to strong magnetic fields just like the magnetic tape memories. The article also mentions that the heat generated is significantly low, so it could be made to operate at higher frequencies, if technology permits, without the risk of overheating."

Its a good practice to install the applications on the device's internal memory instead of installing it on a removable memory. The advantage of having portable memory cards is that you can plug the card into different devices if you want to share what's on them. However if you have some device specific applications on them, you won't be able to use those apps if your card is being used in a different device.

Some of them seem to be in favor of open sourcing their work in order to share ideas and lower the costs involved in solving crime and managing the gathered intelligence."
