It depends on a seller. Some refurbished comes with warranty (Apple is doing that) so this is definitely and advantage. Technically refurbished computer, by definition, should be in a state as close to "new" as it was possible. This of course varies from seller to seller so the best would be to buy it from official vendor. Many big brands like Apple, HP, Dell and Lenovo are having refurbished sales and I can highly recommend those. With 3rd party vendors it can be tricky and it entirely depends on the seller so be careful.
