Remember to keep up on the latest PC news at the Windows Experience Blog, and by following Ben the PC Guy on Twitter @BenthePCGuy.

At the moment, the Signature PCs are only available at the retail outlets – no word if this will also extend to the retail website in the future. In the meantime, we think it would be great if you could get all this software available as a single downloadable bundle – something like Ninite does for third-party programs but with more of a Microsoft focus. What do you think?

In addition to the PCs category, the online store has also added select 3rd party software, accessories,  and gaming products, including a lot of the top selling Xbox 360 titles, reports Trevin Chow, the Senior Lead Program Manager for Microsoft Store.

The store has also been given a revamped interface designed to simplify navigation. The new site offers a re-designed categorization, navigation, and filtering system that aims to help you find the products you need more quickly.

These additions and changes have been added thanks to numerous usability studies and direct customer feedback about what they would like to see in the store – data which has been collected since the store’s launch in November of last year.

After visiting the new store, you’re invited to provide feedback by sending a tweet to Trevin with your thoughts.

The X50 is only 1.4 inches wide and includes a built-in 1.3 megapixel webcam, 15.6” touchscreen, Intel's Atom 330 dual-core processor, 1GB of system memory, a 160GB hard drive, Intel GMA950 graphics, and I/O ports on the two sides. It runs Windows XP Home Edition.

I don’t see any pricing info yet, but at CES it was rumored to be around $500. At that price, this “netbook of PCs” looks like an attractive option for that extra home PC be it in the kitchen, kid’s room or wherever.

Here’s what I have so far:

Asus Eee PC: Asus is responsible for starting the whole netbook trend in the first place. The current version of Eee PC, the 901, can run either XP or Linux and comes in 6 colors. The screen is 8.9” and has a resolution of 1024x600 pixels. The hard drive is a solid state drive (SSD) and is either 12GB (XP) or 20GB (Linux). Other features include a 1.6 GHz Intel Atom processor, 1 GB of RAM, integrated webcam, 802.11 b/g/n Wi-Fi, and Bluetooth 2.0. Weight is 2.43 lbs and battery life is “up to” 8 hours, but Engadget says they only got 4.38 hours out of it. Price: $599

Asus S101: Another Asus netbook is the slim 0.7” thick, 2.2 lbs Asus S101. This portable has a 10.2” screen backlit with LEDs and a resolution of 1024x600. The XP model has a 16 GB SSD and Linux models offers both 32 GB and 64 GB models. Other features include 802.11n, Bluetooth, 1 GB of RAM, an Intel Atom processor, multitouch trackpad, 4-in1 card reader, 20GB free online storage, high quality speakers, and a 5-hour non-replace battery. It’s available in brown, champagne, or graphite. People are calling this one the ‘Macbook Air you can afford.’ Bingo. Price: $699 (XP), $699 (32 GB Linux); $799 (64 GB Linux)

Dell Inspiron Mini 9: This one is Dell’s first attempt at a netbook. Let’s see how they did. The Mini 9 is only 2.2 lbs and 9” long. The screen is a glossy 8.9” with an LED-backlit 1024x600 resolution. Like other Dell computers, you can get Ubuntu or XP pre-installed on either a 4, 8, or 16 GB SSD. Other features include an Intel Atom N270 1.6 GHz processor, 802.11 b/g Wi-Fi, a 3-in1 card reader, Bluetooth, either a 0.3 or 1.3 megapixel webcam, and 2 GB of free online storage from Box.net. Battery life is only 3 hours.  Comes in black or white. Here’s a great review. Price: $349 (Ubuntu), $399 (XP)

Note: If you’re looking to buy a Dell, it might be worth waiting for the upcoming Dell E Slim, rumored to sport either an 8 GB SSD or 40 GB HD with Bluetooth, Wi-Fi, and perhaps even WiMAX. (See a leaked pic on Engadget) 

MSI Wind U120: The 120 is the latest in MSI’s netbook PCs, but won’t be out until December. The netbook will replace the older model, the U100. Specs are still somewhat speculative, but most are in agreement that the U120 will have the following: a 120 GB hard drive or 20/40 GB SSD, 802.11n Wi-Fi, and a built-in 3G modem that accepts a SIM card. Beyond that, the U120 should be very similar to the U100: 1.6 GHz Intel Atom CPU, 10'’ 1024x600 display, 1 GB DDR2 RAM. Will it still have the U100’s 3-cell battery? Unknown, but the 3G might be worth waiting for. (img credit: Fudzilla) Price: Less than $600 (rumored)

Lenovo IdeaPad S10: Although netbooks tend to be for consumers, Lenovo, the maker of business PCs has jumped on this trend. The 2.4-pound S10 has a 10.2” 1024x600 LED-backlit screen, 1.6 GHz Intel Atom processor, 512 MB or 1 GB of RAM, Wi-Fi, Bluetooth, ExpressCard, 4-in-1 card reader, 1.3 megapixel webcam, 2 USB ports, multitouch touchpad, and 80 GB hard drive. Battery is available either as a 3-cell (3 hours) or 6-cell (6 hours). Comes in black, white, or fire-engine red. But the best feature of this netbook is the price. Price: $399 (or $450 for 1 GB RAM + 160 GB drive)

Acer Aspire One: The 2.2-pound Aspire One is Acer’s first netbook offering. The portable offers an 8.9” 1024x600 display and comes with a choice of 80 GB hard drive (XP) or 8 GB SSD (Linux). Other features include a 1.6GHz Atom N270 processor, 512 MB DDR2 SDRAM, 802.11 b/g Wi-Fi, ethernet, 3 USB 2.0 ports, one free mini PCI slot for WWAN, either a 0.3 or 1.3 megapixel webcam, and either a 3-cell or 6-cell battery for 2.5 or 5 hours, respectively. Comes in five colors (white, black, blue, brown, and pink). Price: $379 (Linux), $388 (PC)

Avaratec Buddy: The Averatec Buddy is a 10.2” netbook featuring a 1.6 GHz Intel Atom N270 processor, 1 GB DDR2 RAM, 802.11 b/g Wi-Fi, Ethernet, a 1.3 megapixel webcam, a 4-in-1 multicard reader, three USB 2.0 ports, and a 160 GB hard drive. Has a 3-cell battery and comes in black and white. Runs XP. Price: $450

HP 2133 Mini-Note: The HP Mini-Note is 2.63 lbs and 1” thick with a 8.9” display. There are all sorts of configurations available starting with a Via processor, 512 MB RAM, Linux, and a 4 GB SSD for only $399. At the top end, the netbook runs Vista and include a 1.6 GHz Via processor, 2 GB DDR2 SDRAM, a 120 GB hard drive, a VGA camera, and a 6-cell battery ($799). However, one of the mid-range offerings might be the best fit like the 1 GB RAM/120 GB HD/XP option for $499. The prices on these just dropped, so they might be in for a refresh soon.

This isn’t a comprehensive listing, but just a few that I’m looking at now. I have to admit, this is a tough choice! Feedback appreciated.
