It's worth remembering that health & safety rules prohibit employers from providing their employees with laptops for regular office-based work, since it's impossible to adopt a genuinely comfortable position when using a laptop. Obviously such rules don't apply to domestic use but anyone using a computer at home for prolonged periods should always use a desktop to avoid the health problems which can arise from extended computer use.

Unless you need high-end processing capabilities (e.g. for professional level video editing), I'd suggest buying a refurbished Windows 7 PC (which you could then upgrade, for free, to Windows 10 if you so chose). This is where I buy from:

(That's an excellent company, both in terms of product quality and customer service. I've bought loads of stuff from them, both for myself and on behalf of others, and I've never had a problem).
