Looking for laptop to learn Sql server/SSAS, Tableau etc. Budget around $350 so suggestions on where to get refurbished etc appreciated. Based in Florida.

• Total budget and country of purchase: $350, Florida USA.

• Do you prefer a 2 in 1 form factor, good battery life or best specifications for the money? Pick or include any that apply. Good battery life would be great, but at this price point I think I need to prioritize spec.

• How important is weight and thinness to you? Not much bothered.

• Which OS do you require? Windows, Mac, Chrome OS, Linux. Windows.

• Do you have a preferred screen size? If indifferent, put N/A. N/A

• Are you doing any CAD/video editing/photo editing/gaming? List which programs/games you desire to run. None of the above. Will run SQL Server incl SSAS/SSIS, Tableau, Python, R.

• If you're gaming, do you have certain games you want to play? At what settings and FPS do you want? N/A

• Any specific requirements such as good keyboard, reliable build quality, touch-screen, finger-print reader, optical drive or good input devices (keyboard/touchpad)? Good keyboard would be great as will be typing a lot.

• Leave any finishing thoughts here that you may feel are necessary and beneficial to the discussion. I presume with my budget I'll need to go second hand or refurbised, so suggestions for what to look for, or where to get refurbed gear would be great. I looked at this guy (plus adding some RAM) but I read I'll need four cores and this one is only two.

Thank you in advance to all who read and to all who reply.
