It’s always interesting to know how much a device costs to actually build, compared to what you pay for it and what it is capable of. In the case of the now available Nintendo 3DS, research firm iSuppli has the answers.

They have taken a 3DS apart to figure it all out. The most expensive parts inside are the Sharp screens estimated at $38.80. The processor is about $10, and the memory subsystem costs about $8.36. The user interface with a gyroscope costs $6.81, $5.00 for a WLAN system, $4.70 for the cameras, and about $3.50 for the battery system. The total cost is…

TomTom’s latest offering is the Pro range featuring large 5-inch screens and WORKsmart solutions for mileage registration, time registration, and job status reports. They also have IQ Routes and Eco route capability and Advanced Lane Guidance in addition to support for text-to-speech and hands-free calling. You also get vehicle tracking, job dispatch, time management, and fuel management. Those are some nice features, but that isn’t all.

It includes the PRO 7150, 9150 and 7150 TRUCK purchased via business partners with TomTom. The 7150 will cost you 359 euro, the 9150 is 429 euro, and the 7150 Truck is 399 euro. The TRUCK versions even allow you to pick a road that your big truck can fit on, which is pretty handy.

Mozilla has announced they have released Firefox 4 for Android. It’s also available to download for Maemo devices. Mozilla says that Firefox 4 is up to three times faster than the stock browser in Android, so that is definitely good news.

There are also major enhancements to the JavaScript engine, which is designed to make sites load faster. The mobile version is built using the same technology as the desktop version, and offers tabs, one touch bookmarking, and a whole bunch of browser controls. Sounds awesome. We can’t wait to try it.

The MIX Wireless Mini HTPC keyboard mouse is a palm-sized 2.4GHz RF wireless keyboard which only needs batteries and a free USB port to operate. So obviously it makes a good choice for HTPC use.

The device features an optical touchpad, so you can interact more easily with your operating system and it will operate from within 10 meters of range. The device measures just 109mm x 59mm x 18mm and weighs just 93 grams.

BenQ Japan, like it has done so many times before, has launched the new BenQ BL2201PT 22-inch multifunction LCD monitor on the Japanese market. This handy 22” LED Backlight Monitor goes by the model number BL2201PT.

Those who live in Japan will be able to purchase this WSXGA+ monitor starting March 31st, 2011. It’s priced at 19,800 Yen and the BenQ BL2201PT features a 1000:1 contrast ratio along with a 5ms response time.

We have word directly from Motorola that the Xoom tablet will be arriving in the UK next week. We don’t have an exact date, but you will be able to find it at all the major electronics retailers like Dixons and Carphone Warehouse.

Pricing should be about £500 for the WiFi-only version and £600 for the 3G-equipped version. We don’t know which will be coming next week. Maybe both. It won’t be long now until the first Honeycomb tablet will be on sale.

Samsung has launched their new premium SD card and microSD card range in South Korea. Samsung’s memory cards are known for being rugged and reliable so you can count on them. They will be available in two categories, Essential and Plus. Class 4 for Essential and Class 6 for Plus. And they come with a limited warranty.

The cards range in capacities from 4GB to 16GB with a read speed of up to 17MB/s and a write speed of up to 13MB/s. The cards are water-proof, magnet proof and dust proof and will survive temperatures from 85C to -40C.

Remember that Atari in a guitar hero guitar that I made awhile back? Well, here someone has crammed a full PC inside of an actual guitar. This mod comes from Journaldugeek user Joss.

Joss squeezed in a Intel Quad Core Q6700, Asus motherboard, 4 Gigs of RAM, 80GB raid, a MSI 8800 GTX graphics card and a 650W PSU Thermaltake Blue Evo power supply in a low range Ibiza guitar. Playing PC games on this thing would be very fun.

Earlier this morning Amazon rolled out their own music streaming service called the Amazon Cloud Player. If you are an existing Amazon customer in the US, you can upload your MP3 purchases to your 5GB cloud space. It’s upgradable to a one-year 20GB plan for free when you purchase an MP3 album and additional plans start at $20 a year.

The other good news is that this service is free of charge too. Those other big guys will have to do some catching up here. We won’t mention any names. This should help you clear some hard drive space and keep those tunes safe.

Acer’s Iconia-6120 is amazingly drool worthy. Those who have been waiting to preorder in the US and Canada now have a price and release date. It will run you $1,199.99 and for that price you get a touchbook with two 14-inch Gorilla Glass touchpanels, a Core i5 CPU, 4GB of memory, integrated Intel HD graphics and 64-bit Windows 7 Home Premium.

Other features include USB 3.0 support, a 640GB hard drive, a 1.3 megapixel camera, 802.11b/g/n WiFi, HDMI output, and gigabit Ethernet. Amazon and other e-tailers should be taking orders right about now.

We may have more iDocks then there are iThings in existence, but we still need more. JBL is here to fill that need. The company has just unveiled its first iPad speaker dock, the OnBeat. It’s compatible with iPod touches, iPhones and iPads. We aren’t sure about the iPad 2.

It will provide music of course, but it will also stream Netflix and YouTube content directly to your television via a composite video output. The 3.5mm auxiliary jack makes it compatible with other devices as well. It will cost you $149.95 and it ships next month.

There are large touchscreens, and then there are large touchscreens. Microsoft isn’t fooling around with this humongous beast. At the CeBIT 2011 show in Hanover Germany, Microsoft, with the help of a company called Stereolize, showed off ‘Microsoft Cinema’, basically a giant 234-inch touchscreen display.

It has more area than anyone, even an NBA player could touch, but we assume that the touch functionality goes all the way to the top. Pretty impressive if you are the Jolly green giant.

The 3DS just went on sale over the weekend here in the US, but the console has been available in Japan since February 26. But are they tired of it yet? It’s starting to look that way. Japanese retail blogs are reporting that the handheld keeps being sold back to stores.

That isn’t good news for Nintendo. So, what is the reason? The black screen of death? Well, it seems that there are many reasons that users are ditching the console. There’s the lack of good games for one, even though that will change. Maybe there is just a general disappointment after the buildup.

Thanks to an internal corporate memo, we know that Apple is planning a deal with Radio Shack. About 500 stores US-wide are due to start carrying the iPad 2 on Tuesday, March 29. This is apparently a last-minute plan that had only been agreed upon in the “last few days.”

The company had a much wider launch with the iPad 2 than it had previously. Usually Apple waits until supply shortages have settled down or until it gets closer to the holidays, when the expansion can have a maximum effect. The more aggressive launch is likely due to battling Android tablets like the Motorola Xoom.

Some leaked images and specs of an upcoming LG handset have been leaked. The handset will feature the same Nova display as the current Optimus Black, but at a larger 4.3 inches. That’s why the phone is being called the LG Optimus Big.

It’s expected to launch at Korea’s U+ provider in April. Some of the leaked specs include a 1GHz single-core CPU and a T-DMB TV tuner, which allows watching over-the-air TV broadcasts. That last feature insures that the handset won’t be coming to other markets. At least not without some major changes.
