If you have been holding out for a new ultraportable notebook running Windows 7, today is your day. Windows 7 launched officially today and hoards of new notebooks are hitting the market with the new OS installed. Among the new notebooks is the Dell Inspiron 13z.

The machine is now available in Australia and we expect the machine to be unveiled soon here in the US. The notebook has a 13.3-inch 1366 x 768 HD resolution LED backlit screen. Processor options range from Pentium dual-core parts to Intel Core 2 Duo Su9400 on the high-end. Available RAM is up to 4GB with 2GB standard and storage ranges from 160GB to 500GB.

Dell has announced a strange one today. A Dell mini that sports designs based on Nickelodeon’s Slime motif and hit shows like SpongeBob SquarePants and iCarly. You are probably already familiar with the Dell mini 10.1″ specifications, but obviously Dell is aiming these at children.

Dell says that they want to help provide a safe computing experience, superior educational content and a world-class entertainment experience. What do you think? Are you buying your kid one of these?

Dell’s customizable addition to their Inspiron line will give you way too many color options to choose from. These include the 537 and the 537s. You have eight color choices in all and your choice of Intel Celeron, AMD Sempron, Core 2 Quad and Phenom X4 CPUs, up to 8GB of RAM, integrated Intel graphics or ATI Radeon GPUs, and up to 750GB HDD for the slim tower and 1TB for a mini-tower.

Or you could always just fire up the Della site with a gallon of ice cream and peruse what they have there. The starting price is $299 and they’re all available now.

Dell first started out as a maker of computers that users could customize with the exact hardware that they desired. Dell made its name on the customization options it offered buyers. More recently, Dell has been letting shoppers customize not only the hardware inside the notebook or desktop, but has been offering custom colors and designs on the exterior of the computer as well.

Dell has announced new Inspiron desktop computers called the Inspiron slim and mini-tower. The new machines can be customized with eight different colors that completely cover the front panel of the computer. Dell says it is the only major computer maker allowing users to color customize a desktop computer.

If you’re looking to pick up the Dell Inspiron Mini 10, why not place a pre-order for just $299? While this netbook has not yet shipped, at least you know that your $299 will get you the following: An Intel Atom Z520 1.33MHz processor, 160GB hard drive, 1GB RAM, 3-cell battery and Wi-Fi connectivity.

Thanks to an agreement with Microsoft, the Inspiron Mini 10 will be powered by Windows XP Home Edition and comes in black. You can always pay more if you want a different color or faster processor.

Lately Dell has gone a little artist crazy with new colors and art for many of their models, so it’s not very shocking to see the Inspiron Mini 9 and 12 get into the action. There are five patterns by artist Tristan Eaton, with the same stuff you are familiar with under the hood. These painted Minis will run you an extra $50 over the base price of the regular models, $349 for the Mini 9 and $549 for the Mini 12. I’m sure you can’t contain your excitement.

Dell just officially announced a new member of the Inspiron Mini family, the Inspiron Mini 12. This is either a 1.3GHz Atom Z520 or 1.6GHz Atom Z530 processor, up to an 80GB drive, 1GB of RAM, Bluetooth / WiFi, Windows Vista Home Basic, Webcam and a 12-inch, 1280 x 800 display. The whole deal weighs just 2.72-pounds and is less than one inch thick. Don’t get too excited just yet. It’s Japan-only for the moment, but late next month it will land in the States with a starting price under $600. At that price with it’s performance, it may just be able to snag sales from the Envy 133 and MacBook Air.
