Is it for home use, work, gaming, or even art? Work computers have different uses and different needs, from cash registers to high-end computers capable of performing real-time 3D animations. Creativity and tablets definitely go together for artists, especially in regards to Apple and Windows devices -- artists can now use high-powered tablets with various types of styluses for art, most notably Microsoft's digital pen for Surface Pro and Apple's digital pencil for iPad and iPad Pro; there are even digital paintbrushes of various sizes and types. With a Windows machine you can work in the full version of Adobe's Creative Suite programs, whereas with Apple's iOS devices also have a rich amount of apps to choose from. For high-end gamers, choices may be more limited, Windows or Linux are the best choices here, with Windows in particular getting the most games and sometimes getting a given game first. Dell's Alienware division specializes in laptops and desktop PCs that look futuristic and are high-powered enough to handle the most processor- and memory-intensive games available, although as a gamer it may be better to build your own. You have the choice between desktop, laptop, tablet, or hybrid. Hybrid PCs can be clamshell or other models of laptops that can transform into tablets, like Lenovo's Yoga or the Surface Book from Microsoft. Rest assured, you can also get standard laptops and desktop machines, too; these older style PCs are a lot cheaper than they used to be unless you tack on snazzy new features such as touchscreens, built-in cameras, fingerprint readers and even face recognition login software some of which you may not need - a touchscreen isn't terribly useful on a desktop monitor, for example. Mac OS X only runs on Macs (or Windows via Hackintosh, but the legal status of this is questionable), whereas with Windows you have many more choices of hardware manufacturers and configurations. This is because Windows supports a vast amount of modern hardware natively. Some particulars to know about your various choices include: When considering Mac or MacBook, know that Apple's OS X is based on the FreeBSD variant of Unix, and as such is a stable, smooth-running operating system not prone to anywhere near the amount of viruses or "glitches" that makes Windows so famous for being buggy and insecure. Apple makes simple-to-use but powerful Mac desktops and MacBook laptops. Unlike with Windows there is no Mac tablet available, exactly: iPad and iPad Pro run iOS, not OS X, and so you cannot use Mac apps on iPad or iPad Pro. Windows PCs and tablet computers are the most prevalent computers used for home and business. From Microsoft's Surface Pro tablets and Surface Book laptop/tablet hybrids to similar devices from HP, Dell, Lenovo, and other Windows PC manufacturers, these devices are all backed by the wealth of Windows software available on the market. Google's Chromebook is essentially an Internet terminal that runs Internet-based apps, such as Gmail and Google Docs, and runs the open source Chrome operating system that's based on Linux. Chromebooks -- and Chromeboxes, their desktop equivalent -- are typically less than $1000 -- and in some cases less than $200. Linux is a free, open source operating system that gives you access to the very center, or kernel, of the operating system. You can install Linux on just about any Windows or Mac computer, and Linux is the foundation of both Google's Chrome and Android operating systems. There are a wealth of free apps available for Linux and many different versions, called "flavors" by Linux faithful, of Linux to choose from. Firstly, if you want your computer to be a tablet, Apple offers iPad and iPad Pro, but as mentioned earlier the iPad won't work with Mac software you may have, such as the full version of Microsoft Office for Mac. Windows tablets offer the full version of Office and the wealth of Windows applications on the market in tablet form. However, iOS devices (iPhones, iPods, and iPads use the iOS operating system) have a wealth of apps in the iTunes store and Android devices also have a wide selection of apps in the Google Play Store. Most of the newer, more powerful computers cost well over the $1,000 to $2,000 range. Remember, though, that with a desktop PC in particular, and to a far less degree with laptops, you can choose to upgrade the machine later and so don't have to spend a fortune immediately as long as you get a system that can be upgraded later. Also bear in mind that the more powerful a device is, the likelier it is to cost more; put simply, if you want a gaming-level machine in your hand with a ton of RAM and a powerful processor, you'll pay more for it. This has a lot to do with your price range; you can save a significant amount of money buying something a year or so old, particularly as fast as technology moves in today's world, but if you want brand-new with a warranty you'll pay more. Don't need a huge screen? Don't pay for one. Need a lot of random access memory (RAM) but not too much processing power? You decide. Play around with purchasing tools at your favorite manufacturer's Website (e.g. Lenovo.com, HP.com, etc.) to see what different options cost and take those off you don't need to see how much you can save towards your pocketbook or towards features you want to beef up, such as processor power, RAM, or whatever. If you want to customize your purchase, you really can't do so buying a used computer unless you're buying refurbished equipment from the manufacturer. Some mobile devices in particular aren't very customizable, such as the iPad Pro, Android tablets, Chromebooks, or Windows tablets; however, you will typically have multiple configurations to choose from at different price points.

If you have social anxiety, getting a job that avoids people altogether is not the best idea, as this will isolate you and exacerbate your fears. Instead, you'll want to find a job that puts you in touch with people on a daily basis without over-taxing you. Look for jobs with: Low stress levels Avoid intense, high-pressure environments that will feed your anxiety. Low noise levels Loud noises trigger anxiety in many people. Few interruptions Too much multi-tasking is another common anxiety trigger. Look for jobs that allow you to focus on one task at a time. Limited interaction with other people While you don't want a job where you're interacting all the time (like a cashier or call-center operator), you also don't want a job where you are isolated. Look for jobs that stress one-on-one interaction. Few group projects Group projects not only force interaction, they also increase uncertainty, another source of anxiety. Writing or computer programming jobs are natural fits for anxious people. However, make sure you still have some interaction with people on a daily basis, or these jobs can make your fears worse. Some good low-interaction jobs that still require some interaction include: Lab analyst Actuary / accountant Financial analyst Construction inspector Graphic designer Website creator Cleaning offices Most people with social anxiety find it easier to handle interactions if they are with one person at a time, with no time pressure. Some jobs that favor one-on-one, uninterrupted interaction include: Tutoring Counseling Financial advisor Electrician, plumber, brick mason, etc. Nanny or caregiver Childcare might seem stressful, but many people with social anxiety find it much easier to be around children. Similarly, working with animals (vet or shelter), or with nature (landscaper, nursery, environmental scientist, ranger) can be soothing for people with social anxiety.
