UPDATED 1/22/21 - I've raised the review to five stars... the less than $200 price tag is well worth the cost. This purchase is not for the ignorant. You need to know the basics of Windows 10 to really get it up and running. You will need a monitor, mouse, keyboard, speakers and an external drive (depending on backup needs. Unless you want the very finest cutting edge graphics, this unit is perfect.OLD REVIEW-Two out of the three still work well. The first one died after a few years.Took a gamble on this refurbished 990. Everything works fine except for two things: 1. I couldnt bluetooth headphones - You will need to buy a USB Bluetooth Interface; 2 Cut and paste didnt work properly from one platform (Google, Citrix,WhatsApp) to another. I had to use old Windows apps (Autohotkey) to get around that problem. Otherwise the $ 250 pricetag was well worth the above shortcomings. For persons whom have a monitor and speakers and you dont want to spend exorbitant amounts of $ on laptops, this unit is perfect. Although it is refurbished it works well and is suitable for ZOOM use in lieu of a laptop. I bought two so far and the $250 approximate price is well worth it. One word regarding the WIFI antenna- you need to be careful plugging it in and out. I recommend you plug in the USB antenna in the rear and away from any walls as it is fragile... replacememt could cost you $20
