As part of this, the touchscreen interface is now a major factor in navigating the user interface. Sure, the same tasks can be done through a mouse and keyboard but some of the fastest and easiest method still involve touch. Windows 7 integrated touch controls into the operating system as well but it differed because it was much more focused on emulating the mouse pointer. With Windows 8, it is much more about multitouch gestures.
Obviously if you are purchasing a Windows 8 based tablet, you will be getting a touchscreen based display. But is this a feature that should be critical for a laptop or desktop computer? This article takes a look at the pros and cons for the other computer formats to help buyer's decide if this is a critical feature.
This seems like the most obvious area to get a system with a touchscreen and the benefits are quite tangible. Navigating around applications is much easier than trying to use the trackpads that are built into the laptops below the keyboard. In fact, many of the the trackpads do support multitouch gestures to make switching between applications easier but the support on many of the laptops is too sensitive or just lacking that it is far easier to do these tasks by using a touchscreen. In fact, there is a wide selection of models available from manufacturers that now come with touchscreens specifically because of the new operating system.
While the benefits of the touchscreen are quite easy to see, many people don't necessarily see the downsides of having one. The most obvious of them though is the frequent need to clean the screen. Touching a screen ends up putting a fair amount of dirt and grime on the display panel. There are advanced materials and coatings that can help to mitigate the problem but the glossy coatings already show a fair amount of glare and reflections and the smudges will just make the problem even worse especially if that laptop is used outdoors in bright light or in office environments with their bright overhead lights.
Another drawback that isn't so tangible is battery life. Touchscreen displays draw additional power at all times to essentially read if there is any input from the screen. While this power draw might seem small, it does offer a consistent power draw that will reduce the overall running time of a laptop compared to a similar setup without a touchscreen. This reduction in power will vary from as little as five percent all the way up to twenty percent of overall running time depending upon the battery size and the power draw of other components. Be sure to compare estimated running times between touchscreen and non-touchscreen models to get an idea. Just be warned that many companies aren't always so accurate in their estimates.
Finally, there is cost. On average, a touch enabled version of a laptop may cost roughly $100 to $200 more than a non-touchscreen equipped laptop. This isn't necessarily a huge cost increase but when more and more people are looking at tablets as an alternative to a laptop, it makes the price gap between the two even larger. Sure, there are some low cost options out there but buyers are generally sacrificing other features such as CPU performance, memory, storage or battery size in order to get the touchscreen.
Desktops fall into two distinct categories. First you have the traditional desktop tower system that requires an external monitor. For these systems, it is pretty definitive that a touchscreen isn't all that much of a benefit. Why? It all comes down to cost. Laptop displays are typically smaller which makes it much more affordable to convert it to touchscreen without adding a huge cost. Desktops in general have much bigger screens with 24-inch LCDs being the most common right now. Just looking at that monitor size, the average 24-inch touchscreen is over $500. In contrast, the typical standard display is just $200 or less. That is over a $300 price difference between the two, enough to actually purchase a low cost tablet in addition to the desktop with standard display.
While traditional desktops with their external displays are easy to say that they aren't well suited to touchscreens, it isn't as cut and dry for all-in-one desktops that integrate the computer into the display. They still do have the price markup on them but the pricing gap tends to be smaller than that for external displays. Of course, this is also dependent upon the size of the display for the all-in-one PC. Smaller 21 to 24-inch models will have price gaps of around $100 to $200 like laptops but the much larger 27-inch models will have much higher $300 to $400 price jumps. This price difference can be mitigated by using optical sensors instead of capacitive touch sensors but they don't offer the same level of accuracy or as attractive designs.
Just like laptops, all-in-one touchscreen systems have similar issues with having to frequently clean the screen of dirt and grime. Most feature glass coating on the displays that are more reflective and therefore show glare and reflections more readily. The fingerprints and swipes will tend to show these more depending upon where the system is positioned and the surrounding light. The problem isn't as bad as laptops that are moved frequently but it is still there.
Now the touchscreen displays of all-in-one PCs much easier to navigate between programs and perform certain tasks thanks to the mutitouch support, it isn't necessarily going to be as critical of a feature thanks to more accurate mice compared to the small trackpads on laptops. If you have been using Windows for some time and are familiar with the shortcut keys, then the touchscreen features will be less useful. This is especially true for switching between applications and copying and pasting data. The one area where the shortcuts won't be as effective is launching programs since it is highly dependent upon the start screen and the charms bar.
The advice that I give on Windows 8 systems with touchscreens comes down to which type of computer you are purchasing and how familiar you are with the intricacies of the past Windows operating systems. For laptops, it is generally beneficial to get a touchscreen with Windows 8 but you will sacrifice some running time and pay a bit more for it. Desktops are generally not worth the extra cost unless you are looking at getting an all-in-one system and you aren't familiar with the Windows shortcuts.
