My Dell Inspiron 3470 arrived about one day after I ordered it.  Excellent.  I unboxed and set up the PC yesterday evening (2020-05-07).  I used a 19-in HDMI monitor with built-in speakers (Spectre from WalMart), and an inexpensive Chinese keyboard and mouse.  My Ethernet cable comes to the PC from a NETGEAR GS105 ethernet switch. The machine came up fine.  Getting my Microsoft account reset so I could register the OS was perhaps the most difficult part.  There are a lot of selections to make in the PC set-up process, but just take a deep breath, relax, and get through them.  I did not worry about trying to delete the apps that I will never use.  Maybe later.Unlike some reviewers in 2019, all the software (OS, apps, ….) in my PC is on the high-speed Solid State Drive. That’s good.  The SSD is advertised as 128 GB, which means 128 billion bytes, where this ‘billion” is 10^9, a decimal “gig.”  One GiB is 2^30 =  1.0737 billion bytes, a binary GiB.  So the SSD is really 128/1.0737 = 119.2GiB.  You have to be very careful when reading the displays not to be confused by this difference.  Even then, when you check the Properties of OC (C:) in File Explorer, you get 103GiB.  The reason for this is that there are “system” partitions in the SSD for EFI (the normal “boot sector” – 150MiB), the WINRETOOLS (the “boot sector” for repair tools in case there is something wrong with your system – 516MiB), the System Image (13.68GiB), and for Dell Support (1.26 GiB).  This can be confirmed by accessing the Disk Management app in Control Panel on the machine.  In the OS (C:) partition, which has 103.5 GiB, only 65 GiB is free (from the Properties display).  The other 38GiB is the Operating System (OS), applications software and data, and the normal structure of C: drive on a PC.  Unless you relocate them, all your documents, pictures, and other user data will be stored in the free 65 GiB of SSD.  Keep in mind that photos and videos are big consumers of disk space.Unlike some reviewers, the time from pressing the power-on button to the availability of the PIN-entry window to bring up my machine is seventeen (17) seconds (from cold start).  It comes up from being asleep in about 10 seconds.  I do not have a lot of files to be scanned by the anti-virus software, and coming up may take longer with more stored files.The DATA (D:) drive is claimed to be 1TB, but a Properties test will show it is “931GB”.  This is simply the difference between decimal and binary gigabytes as explained above.  1TB = 10^12B.  10^12B/2^30 = 931GiB = 0.9095TiB.  The DATA (D:) drive on my PC was (and still is) completely empty.  You may want to partition DATA(D:)  for your USER, Documents, and/or Pictures directories,  and/or for Backup files.  Information about the HDD from the OS says the drive is a Western Digital (WDC) device.  If you think you need more storage for files or backup, replace it with a 2TB WDC.  This may, or course, void your warranty.The System Information screen shows that the Installed Physical Memory (RAM) is 12.0 GB, which is what was advertised by Amazon.  The Total Physical Memory is 11.8 GB.  The Available Physical Memory shows 8.37GB.  That tells me that about 4GB is dedicated to something running in the machine.  I think one reviewer said it was used to support the Intel UHD on-board graphics processor.  There are web sites that explain how to increase RAM to 16GB by replacing the smaller DIMM.  By replacing both DIMMS, you could get 32GB or more if you think you need it.The Amazon ad identified the CPU as an Intel i5-9400 running 4.1GHz with Intel Turbo Boost Technology.  I don’t know what that is, but the label on the shipping box and the System Information page from the OS says the CPU is i5-9400 @ 2.90GHz, 2,904 Mhz, 6 Core(s), ….  I do not believe that 2.9GHz is going to be too slow for any of my office applications, but anti-virus software could prove me mistaken.There are two USB ports in front and four in the back.  I had my keyboard and mouse plugged to the back, but attached them in the back through an inexpensive USB hub.  It took about two minutes for the OS to find the drivers for the hub, keyboard, and mouse, but everything is fine.  This same hub was used for a year on a Win 7 HP desktop, but mysteriously ceased working last week.  The Dell 3470 appears to work fine with this hub, keyboard, and mouse.  If you have more than four “slow” USB devices, maybe putting them on a hub to save ports will be a good answer for you.Unlike some reviewers, I found this PC to be quiet.  When the machine is on a desk next to my head, I can hear a faint hum of a fan.  In an office environment, I can not imagine you will hear anything from it.I was able to connect easily to my in-house WiFi 2.4 GHz, but the PC does not see my 5GHz WiFi channel.  I can not tell from the documentation if this PC is supposed to have both WiFi bands.I have not tried the DVD/CD RW drive.In summary, I have had this PC running for a few days, and it seems to be a very good, compact machine.  I am not a gamer: I do not need blazing CPU speed or state-of-the-art graphics.  I run office apps, and may use it for storing photos and other data.  I like that it come up fast.  It seems to do everything I need.
