|Malware||Very little at this time.
As more and more users and business' switch to Mac, hackers will start focusing on Mac vulnerabilities.
|Vulnerable: requires antivirus protection.
Hackers focus on Windows because it is the most popular OS in the world.
|OS Sized||Huge - requires lots of RAM.||Huge - requires even more RAM.||Small and lightweight.
Doesn't require fast processor or lots of RAM.
|Apps||Can run Windows applications.||Proprietary
Has the most available software.
Not as much software available.
|Media||Great running on multi-media.||Best for gaming.||Not as much multi-media apps available.|
|Variety||Current OS||Current OS||Linux is a kernal (core) - requries a Distribution to function. There are several Distribution choices to give Linux a different feel and look: Fedora (Red Hat), Ubuntu, Debian, Mint.|
|Very user friendly.
Unless coming from Windows, there is a learning curve.
|Easy to use.||Slight learning curve.
Also learning curve between different distributions.
|Upgrade||Use proprietary hardware and cannot be upgraded as easily.||Uses standard form factors, easier to upgrade,||Uses standard form factors, easier to upgrade.|
|Apple has it's own help section, and valuable online documentation.
Forums and other support available on the web.
|Microsoft has it's own help section, and valuable online documentation.
As the most popular OS, you can always find infomation or tips on the web.

|Coolness||Best looking hardware.||Depends on Brand, some are cool looking.||Same as windows hardware.|
|Just turn on and use.||Most users also just turn on and use. But OS has capability for Geeks to tweak and play with.||Since one needs to download the OS and manually do an install and setup... A real Geek. You know what you are doing (can purchase pre-installed from Dell, System76, Lenovo)|
Linux has a number of different versions to suit any type of user (Distros).
|Distro||Description||Free or Pay|
|Pop OS||Open-source Linux distribution, based upon Ubuntu, featuring a custom GNOME desktop.||Free|

|Fedora Workstation||Using a distribution made by RedHat, the biggest Linux kernel contributor in the world. Has built in Docker support.||Free|
|openSUSE||Alternative to Ubuntu and other Debian based Linux distros. Makes use of a GUI tool called YaST to install and setup an openSUSE system a breeze.||Free|
|Tails||Its aim is protecting your privacy and anonymity. Because Tails is a live OS, it's actually not installed onto a PC, when you disconnect from the Internet and turn off the computer, there is no trace of activity on your hard drive. All traffic run through the Tor network.||Free|
|Arch Linux||Arch a distro for intermediate and advance users. Not as easy to install, but allows you to customise your build using ability to choose the package to download and install.||Free|

Does not offer much for experienced users.
|Antergos||Antergos is an Arch based distribution and was designed for ease of use.||$2.00 Tip|
Comparison SDD vs HDD
Comparing solid state drive (SSD) and hard disk drive (HDD)
|Boots in seconds.||Slow, may take over a minute.
Depends on heads reading data (if fragmented or not)
|Launches apps fast.||Slower|
|Durability||No moving parts.
Lasts long time.
|Moving parts, susceptible to shock = wears out in time.|
Recommended to disable scheduled defragmentation.
Required for optimal performance.
No moving parts.
9x - 10x lighter
Excellent weight savings for laptops.
Rotating Discs, spindle and motor.
Requries less power = less heat.
Rotaing discs and motor require more power = heat.
Longer battery life in laptops.
More drain on laptop battery.
|Memory Capacity||Up to around 400 GB
Reports of a 800GB by Intel.
|Up to around 4TB
Larger size = more platters for more storage.
Approx $1.50 - $2.00 per GB
Approx $0.10 per GB
