Thanks for all the advice. Couldn’t quite live with the idea of a refurbished item though I’ve bought many refurbs from apple which have been great as is their customer service. Last night I ordered two Lenovo units I didn’t realise that an ssd could be installed so cheaply. The ones I’ve bought are ssd but only 4gb ram which I understand may limit how good they are. Once they are out of warranty I may look into a diy upgrade for the ram. As an aside more than 3/4 of what I was considering are out Of stock with no delivery scheduled thanks to COVID
