Replacement for a Win7 laptop,  no more Microsoft for me.Update 2020 JanAnother update note, two items I've noticed over time.  One, I really miss having a single DELETE key (yeah, I know there's a shortcut of SEARCH - BACKSPACE but it's just awkard).  Two, the weight of the device can be noticeable if you have to carry it around alot.  Still, may be a bit hefty but it gives it a tank quality that you don't have to feel like you have to be extra careful with it,Update 2019 DecAfter using for about a month, I've been more than happy with both the device, performance and reliability.  One thing I would strongly recommend is a buying a higher end port replicator if you want to simplify a room to replace a desktop/laptop environment.  In my case, I plugged in a bluetooth mouse,  a full size USB keyboard,  a USB HP printer, two HP HDMI monitors (one using HDMI interface from the CB the other using DVI adapter).  Additional devices on bluetooth are Bose wireless headphones and UE Boom wireless speaker.  Additional USB connection for 2TBs from a Western Digital MyBook.  Performance has been fine,  no screen lags with an average of 3-4 tabbed pages running on each external monitor in addition to using the Dell CB screen.Wish I had done this sooner ...
