Look at this. Just hours after Barnes & Noble came out with a $149 WiFi-only version of its Nook and a $199 3G Nook, here comes Amazon hitting back in a move that should cut into B&N’s sales.

Now the $259 Kindle 2, with global 3G and the 6-ink E Ink display, is now the $189 Kindle 2. Aside from that you can also enjoy free 2-day shipping. Which will you go for? A nook or a Kindle?

Barnes and Noble has been very busy indeed. Nook owners will want to get this newly released update quickly. Version 1.4 has some important fixes.

Those fixes include the “go to page” feature, an extra large font size for those hard of seeing, and support for AT&T WiFi. Yep, you read that right, free WiFi at AT&T hotspots. The Nook firmware version 1.4 update is available right now.

Toshiba’s AC100 is the company’s first machine to run on Android, and packs an amazing eight hours of battery, or up to seven days of standby life.

It runs on an NVIDIA Tegra 250 chip, with 512MB of DDR2 RAM, and 8GB NAND flash memory. The SD/MMC card reader expands the storage and the 1.3MP webcam with microphone will have you using video-chatting. It’s running Android 2.1 Eclair, has a 10.1-inch TruBrite screen with LED-backlighting, and 1,024 x 600 resolution and weighs 870g.

Great news for Nook fans. Looks like an all-white, Wi-Fi only version goes on sale today for $150. Better news is that the 3G version has also dropped by $60. That means that the classic nook is now $200. The only differences between the $150 Wi-Fi nook and the $200 3G nook are: Wi-Fi vs 3G, the Wi-Fi has a white back, the 3G has a grey back and the Wi-Fi is 11.6 ounces while the nook 3G is 12.1 ounces.

You are good to go with either, but that $200 Nook is worth it just to make sure you have perpetual, free access from anywhere. Great news!

Toshiba has unveiled a thin and very cool new netbook called the AC100. The little machine runs on Android platform and uses the NVIDIA Tegra platform. Toshiba designed the machine to be a take-anywhere unit for active types looking for instant email, web surfing, and more.

Toshiba claims that the machine is good for up to seven days on standby with mixed use. The machine can boot in under a second and with constant use it is good for eight hours.

The original Nook eReader that Barnes & Noble unveiled had integrated 3G connectivity for downloading books on the go. Many people found that they only downloaded books at home and wanted a cheaper device without 3D and Barnes & Noble have complied.

The WiFi only version of the Nook has landed on BestBuy.com. You can pre-order the device at BestBuy.com for $149.99 with delivery by July 3. The device is just like the original Nook sans 3G.

Having a hard time deciding on which tablet device or netbook to buy? Well, you can have the best of both worlds with the Gigabyte T1000P. This 10.1″ touchscreen tablet/netbook hybrid features a 1,366 x 768 resolution which is higher than other displays on devices this size.

It’s available for pre-order from Amazon at $699. Some other features include an Intel Atom N470 1.83GHz processor, 1GB RAM and a 250GB hard drive with Windows 7 Starter Edition as the operating system.

Apple never really wants to tell us how much RAM is in their devices, but MacRumors is now reporting that the iPhone 4 will have 512MB of RAM. That’s twice what the 3GS and the iPad have and is more on par with it’s competitors like the Evo 4G. That’s good news for everybody.

The iPhone 4 will also have the same processor as the iPad, so if this is true it will also have twice as much memory. Developers will be able to keep more data cached and manage graphics changes more effectively, and for you and me that means browsing without frustrating refresh times and smoother multitasking.

Mac users have some good news today. Clear has announced some 4G networking hardware with a focus on Macs. The Sierra Wireless-made 4G+ Mobile USB is its first dual 3G and 4G modem that supports Macs and gives them an EVDO data connection fallback when 4G coverage is poor or non-existent. It will work with Mac OS X Leopard or later and will cost $115 outright or $6 a month.

The Spot 4G is a 4G-only mobile router for those who like to stay in Clear’s coverage. It shares WiMAX with up to eight other devices over W-Fi. The Spot 4G+ is just a rebranding of Sprint’s Overdrive with a 3G option and up to five devices sharing the network.

We know what happens when a radioactive spider bites you. You become spiderman. But what happens when you get too much cell phone radiation? Nothing good, that’s for sure. And so the people of San Francisco will soon have a new cellphone radiation law to help.

The law requires retailers to post notices on how much radiation is emitted by the cellphones they sell. This is the first law of it’s kind in the United States. The cellphone industry claims that this law could hurt sales and make consumers believe that some phones are safer than others. No one can agree on just how harmful cell radiation is.

T-Mobile has announced that it will offer a Father’s Day promotion on Saturday, June 19 where all phones in its stores will be free. That should make dads happy. The phones are free as long as customers sign up for a new family plan or add a line to an existing family plan on a two-year contract. They can get both regular and smartphones without any cost beyond the service.

Handsets will be available on a first-come, first-serve basis. T-Mobile also says that there won’t be any rainchecks or exchanges after Saturday. To be clear, a family plan is made up of at least two users, and up to five free handsets can be put under the deal, each with its own two-year contract.

SuperTalent has a full line of SSD offerings along with lots of other storage products using flash. The company has added a new SSD to its TeraDrive family called the TeraDrive CT. The drive uses SATA 3Gbps connectivity and is aimed at desktops and notebooks.

The SSD supports garbage collection and TRIM command in Windows and promises 285MB/s read speed and 275MB/s writes. The SSD uses the SandForce 1222 SSD processor and features wear leveling.

AT&T has not traditionally offered a bunch of Android devices. This is no surprise given that Android is one of the biggest competitors to the iPhone. Which AT&T sells a massive amount of.

AT&T has added a new entry-level Android device to its offerings today called the AT&T Aria. The Aria smartphone is an Android 2.1 device with HTC Sense UI over the top. The handset has a 3.2-inch HVGA display and operates on the AT&T 3G network with 7.2Mbps speed.

Here’s something you don’t see everyday. Britain’s 3 has added a portable 3G router with its own display features. Huawei’s E585 has a monochrome OLED display that shows battery life and connection as well as the amount of data used. There’s also a new web-based setup page with the router and it can be configured for Linux PCs and Macs and Windows.

The E585 will continue charging even while it shares its 3G connection over Wi-Fi with up to five other devices. It also doubles as storage with a microSDHC slot, but we don’t know if this will act as network-attached storage. 3 UK will sell Huawei’s router in July for £50 (or $74) on a pay-as-you-go basis.

The Samsung B7722 comes packing some cool features along with dual-SIM capability. Some of those cool features include dual standby, a 3.2 inch display screen with touch-sensitivity, Wi-fi, Bluetooth 2.1, FM radio, a 5 megapixel camera with LED flash, microSD expansion up to 16GB, 200 MB internal memory and the TouchWiz UI.

The Samsung B7722 is a good one for social networking as well. It also has 3G. This one will cost you $510 and is not bad looking if you need a dual sim phone.
