Your Old Computer Is Not Dead Yet: How Bangladesh users can save money and keep going

For the past few years, two of the world’s biggest technology companies, Apple and Microsoft, are quietly moving to cut off support for millions of computers that still work perfectly well, especially for low to mid income people and those who really need not to run resource heavy AI tools locally. 

Microsoft has made its latest Windows 11 update incompatible with many older processors while Apple is preparing to drop all Intel-based Macs from its next major operating system, macOS 27. 

At the same time, both the companies have recently raised hardware prices significantly, Apple alone has added roughly Tk 50,000 or more to the cost of a new iMac.

For users in Bangladesh, where a mid-range laptop is worth two or three months’ salary, this creates an unavoidable problem. But it also presents a clear opportunity: a free, open-source operating system called Linux can give those same “obsolete” machines several more years of productive life- without spending a taka on new hardware.
The honest reason older computers feel slow is not the failing hardware. The truth is operating systems and helping software that have grown too resource hungry. 
Windows or macOS installed on a PC or laptop runs dozens of background programmes that consume RAM and processing power before even we open a browser. 

A lightweight version of Linux-based operating system, such as core Debian, Lubuntu, Bodhi Linux etc., uses less than 1 GB of memory when sitting idle. This is roughly one-third of what Windows 11 requires at rest. 
What Linux Means for Bangladeshi Users

It is entirely free, regularly updated, secure, and legal. Over 90 per cent of desktop malware is written to attack Windows or macOS. Switching to Linux means most of those threats simply cannot run on your machine.

For everyday tasks, writing documents, browsing the web, attending video calls, managing spreadsheets, Linux covers almost everything. 
LibreOffice, which comes pre-installed on most distributions, handles all standard Microsoft Office file formats. Google Chrome, Firefox, Zoom, and Telegram all run on Linux without any additional workarounds. 
In Bangladesh, a student, a small business owner, or a journalist with a tight budget will mostly get the benefit of a Linux-based distribution on their old machines. 
To be honest, it depends on the type of machine, but the numbers are encouraging. 
A desktop PC, the kind commonly found in Dhaka offices and residences, has no battery to degrade. Running a lightweight Linux distribution on an older desktop can realistically extend its working life by seven to ten years beyond what Windows would allow, into the 2030s, unless the power supply and motherboard remain physically sound.

Older laptops are a slightly different case. The main limiting factor is the battery. Once lithium-ion cells deteriorate beyond a certain point, the laptop effectively becomes a desktop that requires a constant power connection. 
However, these machines will outlast their chassis. A three-to-six year extension is a realistic and conservative projection for pre-2018 laptops running a lightweight Linux system.

Apple MacBooks from 2019 and 2020 require some intermediate tweakings though. 
A specialised setup through a project called T2 Linux, because Apple uses proprietary security hardware that standard Linux installers cannot read. 
The process might take an hour but, once complete, these machines, which are genuinely high-quality hardware, can run professional workloads for five to eight more years.

On AI: You Do Not Need to Run It Locally
One argument often made in favour of buying powerful new hardware is that artificial intelligence tools require significant processing capacity. But this is not true for most users.

Running a large AI model directly on your own computer demands substantial memory and a modern graphics chip. 
For the vast majority of Bangladeshi users, this is neither necessary nor cost-effective. 
Where a paid subscription is genuinely useful, entry-level plans from the major providers currently cost between $10 and $20 per month. A small fraction of the cost of even a budget new laptop, and a fraction that covers access to far more capable models than any consumer machine could run locally.

So, keep the older machine, install a Linux-based lightweight distribution, and pay subscription if AI assistance is genuinely needed. For most of our works, free tiers are more than enough. 
That combination costs far less than a new device and delivers more AI capability than running them locally.
These unofficial releases circulate widely and are a serious security liability. They receive no official security patches and are frequently bundled with malware by the people who distribute them.
