According to your use and profession If you consider that Ultrabook suits you more than MacBook Air or you are interested to buy an Ultrabook rather than MacBook Air, so there are some actual features your Ultrabook must have.

According to style, features and something that called Trend, Apple's MacBook Air is a top Notebook but on other side Intel's super fast chipped Ultrabooks is more liked because of its compatibility and user friendly environment operating system (Windows).

So you have decided you want to buy an Ultrabook rather than a MacBook Air? Here are 5 top features to consider before making your purchase.

Many of the unique or unusual characteristics about Ultrabooks come about because they're so thin, a height of three quarters of an inch, and even less in some cases. One of the most important of these is the systems' tendency to feel flimsy. Because most laptops don't sit at home on your desk all the time, you want the sturdiest on you can find, whether it's open or closed.

Key travel on Ultrabooks is frequently shallow, after all, there's not a lot of room to house big, strong keys! This won't be a problem for everyone, but if you're a hard core typist or if you are going to need your laptop for work, you'll want to pay special attention to the keyboard. If you can, try typing on an Ultrabook you're interested in before you take it home to get an idea of how it feels beneath your fingers. You don't want to buy a notebook you won't enjoy typing on.

The reduced height of ultrabooks causes problems with ports as well. Many systems simply don't have room for Ethernet ports, some have far fewer USB ports than you may be used to (may be only one or two), and still others may come with dongles that give you the ports but add inconvenience to the package. Knowing what you need, so you know what you'll need to put up with, is an especially good way to go here.

Although not a part of the standard ultrabook specs, and previously impossible to find on many systems, touch screens should now be considered a necessity. The new tile based Windows 8 interface was designed for touch, and the operating system just doesn't deliver the same experience without it. A laptop with a traditional touchpad will work, but it won't be anywhere near as intuitive. To get the most out of your Windows 8 Ultrabook, make sure it comes with a touch screen.

Intel's Wireless Display technology (usually shortened to WiDi) lets you stream HD content over the air to your HDTV, rather than forcing you to connect your set to your laptop with an HDMI cable. You'll need a separate adapter, like Netgear's $100 Push2TV (pictured here), to make it work, but if you're really into entertainment you'll easily find WiDi capability worth the extra investment.

Although Apple's paper thin laptop has quite a bit in common with Intel Ultrabooks, in a few ways we describe below they are significantly different.

Any seriously diminutive system is going to have an extremely restricted port selection. What has really defined the MacBook Air to this point has been its Thunderbolt port, which combines PCI Express and Displayport protocols for high speed connections to devices as diverse as hard drives and external monitors, and is about as small as ports get. Thunderbolt ports haven't appeared on PC based ultrabooks yet, but it's only a matter of time until this changes.

Not that this means there's any chance the MacBook Air will go anywhere. One of Apple's defining (and most striking) products, it's still the first thing people think of when they think of ultrathin laptops and so far no Intel ultrabook has come close to changing that. The biggest threat to the MacBook Air is Apple itself; Can company devise something better to replace it? If not, expect it to continue receiving yearly updates that make it thinner, more powerful, and more exciting.

The Sony Cyber-shot DSC-RX100 is the point and shoot camera that many Professional's dreamed of. With a large image sensor its 3.6x zoom lens opens up to f/1.8 on the wide end, and it can slide into your back pocket easily to carry everywhere you go. The 20 megapixel RX100 picture quality superb that can justifies its cost.

Measuring 2.4 by 4 by 1.4 inches (HWD) and weighing 8.5 ounces, the RX100 is only slightly larger than the Canon PowerShot S100. This is impressive considering that the S100's image sensor is a mere 1/1.7 inches in size, the RX100's 1 inch sensor boasts more than 2.5 times the surface area. Though the lens is fast and the sensor large enough to create a nice out of focus blur behind subjects, you shouldn't expect the RX100 to produce images that are quite as good as those from a D-SLR camera; they are better than you'd expect from a point and shoot camera, but you are still sacrificing some image quality for portability.

The lens is a 3.6x zoom (due to its compact size), covering a 328-100mm (35mm equivalent) field of view. It opens up to f/1.8 at its widest, narrows to f/3.2 by 50mm, and closes down at f/4.9 at its extreme. One of the weak points of the RX100 is its lack of any sort of eye level viewfinder. There's no accessory pot to add one, nor is there a hot shoe. What you'll use to frame and review images is the rear LCD. At 3 inches, it features a staggering  1,1229k-dot resolution, about a third more than a competing 921k-dot displays. Sony has added white pixels in addition to the standard red, green, and blue, resulting in an LCD that is brilliant even when viewed in bright sunlight.

Controls will satisfy the demands of serious shooters, but aren't perfect. Save for the shutter release, zoom rocker, Mod dial, Menu, Playback, On/Off. Display, EV Compensation, and Help buttons, the RX100's physical controls are largely customizable. The front and rear control wheels are a bit quirky when you're adjusting ISO, you need to move the wheel to the left to increase the sensitivity and to the right to reduce it, the opposite of the wheel's usual behavior, but the control system is otherwise well designed.

The Camera's flash hides inside the body when not in use, popping up at the half press of the shutter button once it's been enabled. It sits on a hinged neck, which makes it possible to tilt it back with your left index finger and to bounce light off of a ceiling. It's not powerful enough to act in this capacity in, say, a ballroom, but for snaps around the house using this method will help to soften the light. Of course, there's also Flash Compensation available, so you can reduce the power output to provide just a little bit of fill when you're not using it as a bounce flash.

The RX100 is a little slow to start up, but is otherwise a speed demon, there's virtually no shutter lag thanks to quick, accurate autofocus. When shooting JPEGs in its Speed Priority mode it can capture a burst of ten shots in a second, although if you're shooting in Raw the camera takes 2 seconds for the same ten shot burst.

As measured by Imatest, the RX100's lens helped it deliver highly sharp shots through the entirety of its zoom range with, at most, 0.2 percent pincushion distortion. Noise is also not an issue, it stays below 1.5  percent through the camera's top ISO of 6400. JPEGs look excellent through ISO 800, very good at 1600, and pretty good at 3200; comparing Raw and JPEG files side by side, there's very little evidence of noise reduction in the JPEGs at the top ISO settings.

Video is recorded in AVCHD format at 1080p60 or 1080i60 resolution. The lens zooms in and out quietly while recording, and the focus keeps details clear and sharp.

The micro USB port doubles as a charging mechanism for the battery, and there's a micro HDMI port for connecting to an HDTV. In addition to SD, SDHC, and SDXC memory cards, Sony also supports its own proprietary formats.

The Sony Cyber-shot DSC-RX100 doesn't have the largest sensor of all zooming point and shoots, but it focuses fast, is consistently sharp, and can capture images with a shallow depth of field. You won't find better photos forma a camera that fits in your pocket.
