Speaking for Acer laptops, I understand there are business laptops and personal [home-use] laptops. I have an Antec [?] desktop which can be both business or personal. IMO, there are no clear lines of business level computers and personal level computers. A lot depends upon the functionality, durability, graphics quality, sound quality, screen quality, upgrade ability [hardware], which factory-installed Windows, and other factory-installed software in general, and other factors.
I haven't researched Acer business laptops. I do not know what their current offerings include.
As far as I know, Antec only makes computer cases, power supplies, and some accessories. They don't sell complete computer systems. I have used Antec products in some of my builds.
Some of the differences I (sometimes) see between personal and business computers include:
Business computers do not come loaded with trialware and bloat. IT Departments do not tolerate that.
Business computers feature enhanced remote management features to make managing 50-50000 computers easier for IT Department.
Business computers are usually built to reduce The Total Cost of Ownership. The cost to purchase, maintain, and manage the devices.
Stability and reliability is often valued over peak performance.
Business computers often have enhanced security features for protecting confidential data. The cost of a stolen laptop hardware is not nearly as important as the value of the data on the device. The cost to the company if that data is compromised can be extremely high.
Business laptops are sometimes ruggedized for use in mobile or harsher environments. This can add considerably to the cost of the device.
In some cases, business laptops have been designed to allow the user to very quickly destroy data on the hard drive in the event the need arises.
Business computers can be delivered with a customized hard drive image fresh from the factory.
In some cases, business computer product lines will have the same system components used for a product life span. This makes the above imaging easier. Makes product deployment and management easier.
I have never been responsible for deployment larger than 20 computers. My knowledge of much larger deployments and networks comes from networking with professionals in the industry.
