For Prime Day 2018, Microsoft is offering 34% off its Surface Pro - 2017 model - so you can get the Core i5 model with a Type Cover for just £749.99.
That's £379 off the usual price of the bundle: the keyboard isn't normally included with the tablet so you're not only saving money off the tablet itself, but you're effectively getting a Type Cover thrown in for nothing.
You must be a member of Amazon Prime to take advantage of the deal price.
If you're not too familiar with the Surface Pro, it's one of the best Windows 10 tablets out there. With a keyboard, it turns into a proper laptop, and there's a full-size USB port for connecting thumb drives or a mouse.
It has a 12.3in screen - an excellent one at that - plus 8GB of RAM, a 128GB SSD for storing all your stuff and Windows 10 Pro. The processor is the Core i5-7300U, a seventh-generation chip that runs at 2.6GHz and boosts up to 3.5GHz when needed. It's a dual-core part with Hyper-Threading, so it's effectively a quad-core processor.
It lasts up to 13.5 hours between charges, so it should give you multiple days' use without having to think about connecting to the mains.
