I currently have 4x HP Probook 4520S laptops for my business which runs a basic physiotherapy practice diary program (connected to a main server computer which is a Dell OptiPlex). These laptops are running windows 7 and trying to update them to windows 10 has been a nightmare (error after error). I figured it's been 10 years now so it's time for an upgrade of 4 "new" [Refurb] laptops. I'm not and expert on processors and would like the OzBargain community's input on recommendations on purchasing these laptops. My minimum requirements are: i5 processor, 15.6'' screen (i.e. keyboard with numb pad), windows 10/11 on an SSD hard drive. I came across this on eBay: Dell Latitude 5590.
Will this laptop last well with future updates? Are there any others anyone would recommend (~$600 budget per laptop)? I have been put off all HP products recently mainly due to their bloatware and the problems they cause, so any other brand would be fine.
My other question is, if I purchase 4 identical laptops, will I need 4 separate cd keys for programs such as Microsoft Office or even malwarebytes or will one suffice due to the laptops having the same hardware?
TL:DR What laptop would you recommend for a physio practice to run a simple daily diary program for $600 or less (preferably with a 15.6'' screen and decent processor with windows installed)?
Thank you all on advance.
it's per user, not per computer.
