If you’re in the market for a new all-in-one PC you certainly have options. But if you want one that’s affordable, you may want to check out HP’s latest Pavilion MS214.

This machine is priced at $585 and boasts an 18.5-inch widescreen LCD display, an AMD Athlon X2 3250e 1.5GHz Dual-core processor, an ATI Radeon HD 3200 graphics card, 2GB RAM, a 320GB hard drive, built-in webcam, a DVD burner, a 6-in-1 card reader, WiFi and Windows 7 64-bit as an OS.

Two segments in the computer industry are growing robustly despite the economic downturn around the globe. Those two segments are netbooks and all-in-one desktops. In fact, IDC expects the all-in-one category alone to grow by 12.4% from 2008-2013. Today Lenovo added a new all-in-one to its line called the C100, and it’s cheap.

The C100 will be available this month with prices starting at $399. The little rig gets an 18.5-inch LCD with a wide aspect ratio that is only 2-inches thick and houses all the hardware the typical PC has. Basic machines get an Intel Atom 230 single-core CPU.

A while beck we mentioned that Viewsonic had announced its first all-in-one PC called the VPC100. All-in-one PCs are nice devices that offer all the parts that you need for a computer inside the LCD. The machines are like netbooks on the inside for the most part.

At the time, the PC was announced we didn’t have a ship date from Viewsonic to share. Viewsonic has now announced that the VPC100 is shipping for $599. In case you missed the first post about the product, the VPC100 runs an Intel Atom 1.64GHz CPU, Windows XP home and has an 18.5-inch LCD.

Samsung just released it’s latest LCD monitor dubbed the Lapfit External Display. It connects to your laptop, giving you a larger display to work with, play games,watch porn or whatever. The cursor and image panning are nearly perfectly aligned.

You’ll get 18.5″ of viewing area, and it’s probably a good idea to have a notebook equipped with a decent high-end graphics card so you can take full advantage of it. No price info, but we are guessing it will be comparable to a regular 18.5″ LCD.

We’ve been seeing all-in-one PCs more often lately. The latest is this 18.5-incher, the ZX2300 from Gateway, which should be available in Taiwan soon. The system is powered by an AMD Athlon 2650e CPU that runs on Windows XP Home, and supports 1GB RAM and a modest 160GB hard drive. LCD screen resolution is 1366 x 768.

The 18.5-inch display will give you a 16:9 aspect ratio. The ZX2300 also features Wi-Fi, webcam and a 16X LightScribe DVD burner. The PC will sell for about $530. No word on exactly when it will drop, but those in Taiwan will have a first crack at it.

The largest TFT LCD maker you’ve probably never heard of today said it had developed for its name brand clients the world’s first 16:9 Full HD TFT-LCD with 1920 x 1080 resolution for desktop monitor. Availability for this LCD from Au Optronics is projected later this year, though we don’t know as of yet pricing or who will actually put this panel into retail environments.

Auo’s new 24-inch TFT-LCD offers up a widescreen 16:9 format for better viewing of HD content. It offers up what is described as a “stylish thin and eco-friendly” design and is 1080p capable. Thinness of the display compared with more conventional 24-inch displays measures out at some points to 14mm.
