GNU/Linux: Is it immune to Malware?

When someone switches to GNU/Linux, one of the attributes assigned to GNU/Linux and other Open Source Operating Systems (that are free [as in freedom]) is that GNU/Linux is VIRUS or Malware free.

I have been answering (some of the misunderstandings in this respect) at multiple forums and lists, but here is the comprehensive answer.

The truthful answer is YES, writing and enabling malware executing within GNU/Linux is possible.

I prefer the term Malicious Software (abbreviated Malware), rather than the obscure and rather obsolete term 'Vital Information Resources Under Siege' (VIRUS that sounds like a poorly named movie. )

Literacy: Is it truly necessary?

The letters are easy, yet read the names and words and see that their pronunciation and usage are anything but easy
Many of us schooled in India, perhaps even elsewhere in the world have been told that a good percentage of the population of India is still illiterate. They are literally unable to 'write'. Most of us (at least within the groups I have spoken to) have been taught that the "lack of schools" or the "lack of primary education" is the primary cause of illiteracy.

Nothing could be further from the truth. Indian systems of writing were extremely well developed and evolved. Evidence of a 7th Century CE carving here, shows the "engineered" Grantha script - ('Grantha' literally means script, and is a phonetic script that can ideally be used to represent any language.)  Those who made these carvings that remain today are unlikely to be royalty or even priestly folk suggesting that language was available to artisans and craftsman. Further written scripts were to be taught after the fundamentals of speaking a language was taught.

Laptops: an end of an era

Laptops started out as lightweight portable PCs, but have succumbed to stiff competition from the Smartphone, Tablet and Phone-Tablet (dubbed Phablet) alternatives.

The factors that have slowly taken the laptops close to their extinction are:
  1. Weight (although portable, lugging them over long distances is not comfortable.)
  2. Fragility (except for the rugged versions, most laptops cannot stand shocks)
  3. Upgrades (very minimal)
  4. Battery Backup (extremely low if compute power required is high defeating portability)
  5. Lifetime (3 years at best, but the next generation replacement is seldom as far ahead as the smartphone class.)
  6. Chargers (These are not standardized and vary heavily across brands and models.)
  7. Serviceability (Time consuming and subject to spare part availability)
  8. Thermal performance (Cooling has always been a challenge, with few laptops cutting that edge for those who can afford them.)
  9. Display (Graphics acceleration for several reasons has always been minimal, rendering them less useful for high-end applications like rendering.)
  10. Wireless Communication (Too few are provided with 3G making them less useful in remote environments)
  11. Recycling (the mechanical design is usually less susceptible to recycling, as is the display, input interfaces and storage - with the core motherboard also getting outdated far too quickly. This coupled with the short lifetime is making them less recycle-friendly.)
  12. Software (Operating Systems constantly requiring upgrades make the "Personal" computing part much costlier and less affordable across most available brands. This is also true of most application software used.)
