Hello MrK1, looking to get away with as cheap as possible to just do the job, with the criteria stated. As previous, I have a top of the range Dell XPS 15" laptop, windows 10; offce pro, 42" monitor etc as my main unit. The new device is merely for travelling, but needs to be compatible with the main unit so that I can transfer documents betwen the two units. From what I have seen thus far there is an HP Stream 11.6, which "may" surffice c/w an external hard storage. As you have probably guessed; I am no computer whiz, so probably most of the issues I raise may seem very simplistic to those that obviously know what they are talking about and are in all probability a lot younger than me. I need the device only when travelling in order to deal with some business matters when away (no complicated stuff); order rail tickets on the move (but this can be complicated in the countries I will be going to); sending e-mails when absolutely necessary; etc. I need a key board facility, as I am not used to, nor do I want to use my mobile for such issues as perhaps doing some banking transactions etc (again only if absolutely necessary). Hope this helps.
Well it obviously runs the Apple operating system (ipadOS) but you can get the MS Word, Excel etc apps from the store; there's also other suites of apps which are compatible with .doc etc file formats but if it's essential then I'd stay with the official app. You can link your Google drive or iCloud to both your laptop/desktop and the iPad so moving files is a doddle. Built in email app is good but again if you're using it for work then the MS Outlook app is available. Later incarnations of the iPad have allowed for use of portable storage devices (thumbdrives etc) but I haven't actually ever had the need for them since using cloud storage (one off transfer then the files are available on whichever device I want and the thumbdrive just sits in the drawer)
If you haven't used apple devices before it takes a bit of getting used to (I came from android and currently use an android phone, windows for work and iPad for on the move or wasting time!) but when you're used to it everything works really well if not always intuitively.
Linx 12X64 - 12.5-inch Tablet with Detachable Keyboard Intel Atom x5-Z8350 / 1.44 GHz (1.92 GHz Turbo) Quad Core Processor, 4GB RAM, 64GB Storage, Windows 10 - LINX12X64
I have never used one, so can't comment on the build etc, but it ticks all your boxes. It wont have MS Office on it, so you will need to factor in the licence cost for that unless your workplace will install it for you. Plenty of free software that will allow you to read ebooks on it as well.
Don't expect the same performance as your Dell though.
To keep a long story relatively short, I bought a HP 2-in-1 tablet & keyboard from John Lewis years ago. It died and I replaced it with what I thought was a cheap and cheerful Lenovo i5 SSD laptop (about £450 IIRC). It has been brilliant - boots up in about 5 seconds (faster than the gaming PC that I just built).
SSDs mean that you can get a light laptop with loads of storage. Take a trip down to PC World and have a look.
In terms of reading books, I use my smartphone and download from Amazon Kindle or Google Play store. Probably not as good as a Kindle but I like to travel light. Otherwise my favourite way is the old fashioned paperback.
I have a Kobo Forma e-reader that I can (what is known as) side-load content that comes from anywhere. It can use the Kindle format (mobi) or the usual epub format amongst others (like PDF). I love mine!
I have a couple of Chromebooks (for the kids) but they run on ChromeOS so it may not be fully compatible with your Dell.
Have you looked at the Microsoft Surface Go?
