Warning: this is a long dump of somewhat technical information.
I have a Venue 8 pro on a shelf.
It was pretty good for the price, but not actually very useful to me.
Android tablets were just better for tablet functions.
When I bought it, I wished to run Linux on it. Unfortunately there were a number of barrier.
I have been able to update Windows. I think that I sometimes had to give Windows Update a blank USB stick for temporary files (that was some time ago). Recent updates don’t seem to require extra space (note: almost nothing is installed on my tablet so Windows can have the whole eMMC). Updates are very very slow.
It is possible to boot off a USB stick. Dell sold a special dongle/cable that allowed a USB device and power to be connected through the OTG USB socket on the tablet.
It is not possible to boot off the SD card. I think that the reason is that the UEFI system does not have a driver for the SD interface. Very unfortunate. It should be possible to write such a driver and install it in ESP partition. But I don’t think that anyone has. If that were possible, dual boot with Linux could make sense, with most of Linux living on an SD card.
Recently I successfully booted a live Fedora 35 x86-64 Linux USB stick. It required some firmware (BIOS) settings that prevented Windows from booting (I’ve forgotten which settings). It’s not much fun using a tablet with a dongle plus USB stick hanging off it. So this was mostly a proof of concept.
The hardware isn’t very compelling in 2022, but it still works. 32G of eMMC is the worst limitation, I think.
Very few Linux distros support 32-bit x86 hardware these days. The V8p has a 32-bit UEFI so it expects to boot a 32-bit OS. But the processor is 64-bit. Some time after the V8p was released, the Linux kernel developed the ability to run in 64-bit mode on top of a 32-bit UEFI. That’s why the 64-bit Fedora could run.
64-bit Windows won’t run on a 32-bit UEFI system. I would like to try WSL (Windows Subsystem for Linux) on the V8p but WSL requres 64-bit Windows.
The V8p was part of a generation of Windows/Intel hardware that was intentionally crippled so that it could not compete with more expensive PC systems but was cheap enough to take on Android/ARM. Intel blew a billion or so subsidizing the processors and Microsoft blew even more, including buying Nokia.
There are Windows-based tablets and convertibles, but none at the low price points of the V8p era.
My V8p originally cost C$100 from the Microsoft store (that included a license for MS Office!). Then I bought accessories. Compare that with: I recently bought and enjoy a ChromeOS tablet from Lenovo for C$129.
