The Dell Latitude 6430u is an Ultrabook - basically a very thin laptop - that is only about an inch thick and weighs around 1.5kg. It might not be as light and portable as a tablet or smartphone, but if you are aiming to do real work on word processing, image and video editing or even gaming, I would recommend you use a "real computer" such as this instead of a mobile device.
Speed-wise, it's blazing fast compared to any current notebook and tablet, especially when compared to my three-year-old notebook, which increasingly gives me an itch to throw it out the window. It's so fast that Windows 7 can be booted up and ready to use within 25 seconds (view video at the bottom of this page) and can run all major games to date. Having Windows means that you can do all sorts of things that you're used to doing and run all your legacy software without the need to look for equivalent programs like when you switch to Android or iOS devices. And it was satisfying to be able to play a few missions of Tomb Raider on high graphic settings on a laptop.
Computers have less restrictions and don't have to compromise with screen size and design choices, and this laptop comes with a 14-inch matt screen, which is good for long, serious use; it is much more friendly to your eyes then any glossy screen. Also, the magnesium coating on the exterior gives it a very sturdy and professional feel.
It features a great full-size keyboard which also has backlight to let you see the keys in the dark (the backlight brightness is also customisable). This is a very cool idea, especially for people who want to, or are forced to, work and play in the dark (like me, in compliance with my wife's demands). Together with a touchpad and a touchpoint, you have so many options to control this thing to your preference. So, you can choose how to move your cursors and mouse pointers the way you like. If you don't like both control options, you'll just have to plug in a mouse instead.
With double USB3 ports and an HDMI port, you can plug in a lot of gadgets and extensions to extend the functionality of it too.
As I often let the children watch cartoons and YouTube videos, having nice, loud full-range virtual surround-sound speakers is a big plus. My two daughters really enjoyed watching their favourite cartoon movies on the Dell Latitude 6430u with the volume turned up to make them feel like they were watching their beloved TV set.
This machine can be used constantly for five to 10 hours depending on how you torture it. For normal office work, you'll definitely get through the day without plugging it into the nearest power outlet.
Although it's still quite heavy compared to tablets and hybrid Ultrabooks (models with detachable keyboards), carrying this device around in your bag is not burdensome, though it might strain your shoulders a bit if you do it all day long.
Even though it's capable of installing the latest Microsoft Windows, having no touchscreen makes Windows 8 a bit of a moot thing. I would seriously recommend Windows 7 on it.
This fast machine is a bit pricey, however. It will set you back 41,000 baht. If you really want extreme gaming performance, you can get a fully-fledged gaming PC for that price.
This Ultrabook is aimed at business-orientated people and I think does way more than what they need. I would definitely recommend this to office workers bored with lugging around their weighty bricklike notebooks all the time but who still want all the power of a pretty fast PC on the go.
