Twinhead H12M Notebook

It is really great that new ultraportable notebook prices are more affordable.

Such is the ultraportable Twin Head H12M, for the same price as most notebooks normal size.

It is also one of the first ultraportables to a wide-screen sports, but because of size constraints, the screen is only 12.1in wide.

This means that the screen is not as impressive as the larger on notebooks and desktop replacement, unless you look carefully you might not even notice that there was a wide screen.

Twin Head notebooks H12M The screen is a glossy variety, which looks really beautiful, but it is a bit difficult to use outdoors.

It has a resolution of 1280 x 800pixels, the sharp enough for a screen this size.

Hi-Ho Silver

The Twin Head, I voted for the review was almost completely silver, except for the keyboard, making the usual black.

I have no problems with the color, but I do not think it pleasant for all. In any case, the H12M also comes in black.

Like most new notebooks, the ports are usually on the sides, it is commendable that this is a very small notebook and space is a premium.

Only the modem and network ports are located on the back side, which is not as bad as I focused mainly on its wireless connections (the notebook has both Wi-Fi and Bluetooth) to surf and the transfer of files on my computer.

There are three USB ports on the right side, and they are pretty good distance, so you would have no problems plugging in more than one accessory at the same time.

It also comes with the new Express Card slot, but not the old PC-Card slot - this is just a sign of progress in the industry is that finally away from the old card slot. However, a lot of expansion cards such as 3G cards are still just as PC Cards.

And surprisingly it came with a DVD burner, most companies just a combo drive in an ultraportable - but we are not complaining.

The notebook also comes with a card reader accepts that popular formats such as SD, MMC and Memory Stick.

The only thing the notebook is very short, the quick access keys - it is only an introduction to the Windows Media Player. More would have been better, definitely. And that's not shine in the multimedia department either as the speakers are very soft, but with headphones easily solves.

Hot air

About the only thing I did not like about the notebook is that it is running a little hot after a while - they have not on your lap, if you plan to use it for a long time.

This is because the fan is on the lower side of the notebook, and though a vent is on the side, most of the hot air is channeled down.

All this helps cool the Intel Core Duo processor 2, which is as strong enough to multitasking very well.

Even with the notebook 512MB RAM, I could run multiple applications simultaneously, but I would still prefer to 1 GB of RAM to the future.

Because it is not a game machine, it is based on the Intel Media Graphics Accelerator 950 graphics engine, with all the attendant responsibilities, the graphics produced decent results, as long as you do not stray from the 2D graphics (or basic 3D) path .

Conclusion

The battery lasted for nearly three hours on a single charge, which is very good, when you consider that it is not possible to a large battery pack in a notebook of this size. Plus, the battery is not explode during the review :-)

For what it costs, the H12M value for money, and it does not renounce all features - in fact, it has a powerful Intel Core 2 Duo processor, a wide-screen, sufficient space on the hard drive, a DVD burner and decent battery life.

Pros: Nice looking, Core Duo processor 2; good battery life, very affordable.

How Do Inkjet Printers Work?

Given the advances that technology has been making over the last thirty years or so it is amazing that the Inkjet printer is just now becoming a ho-hum sort of item. The inkjet printer has been around since the early 1980s but needed a few fine tuning advances to make it more affordable to the average user. Since that time in the 1990s, when the advances necessary for mass marketing were found, inkjet cartridges have become the norm. But the question of how inkjet printers actually work, and is it a good thing remains. Of course the answers to these questions are yes, no and maybe.

Two choices

The basic concept behind the inkjet printer lies in the concepts of how printers work. Right at the yaso level we find an answer of; a printer puts printer ink onto a piece of paper or other material. In our case we are talking about getting ink from ink cartridges onto paper in a finely defined color.

Thermal bubble This first choice came largely from the bubble jet era and works by generating a certain amount of heat in the printer ink cartridges. The heat causes a bubble to form which eventually collapses as the printer ink is forced through a nozzle due to the bubble formation. The collapse of the bubble then causes more printer ink to enter for the same process to begin again.

Piezoelectric There is a significantly smaller penetration of this method due to patent rights but the general concept is the same if you are able to connect heat and vibration as thermal equivalents. In this method the printer ink is ejected by vibrating crystals within the jet nozzle as electricity is passed through the crystals. As the crystals vibrate they cause the printer ink to be ejected and replaced by more printer ink. In this particular method there are many more nozzles than in the thermal bubble method so image quality is significantly better. Unfortunately, with the rights issue in place this quality is in limited release which makes the thermal bubble method more preferred.

Costs

The costs of inkjet ink cartridges can, unfortunately, be rather high. In this case the user must look to the cost of the unit if there is to be any noticeable difference in Inkjet cartridges bought. Lower cost machines do have a tendency to have lower cost ink cartridges but quality of the copy is poor. Looking in the other direction, higher cost printers will give you high quality prints but ends up costing you more than the printer in ink cartridges over time.

How inkjet printers work and the quality/cost issues appear to have penetrated the average consumers psyche in the first years of the 21st century. Using an analogy for Americans it is sort of like buying a Chevy (car), You know what you are getting, it is basic and it will last. For an item that has essentially become a commodity this is not such a bad thing. Until the next advance is made, this has been about 30 years in coming.
