The most recent Surface is called the Surface Book 2 and it is excellent, but of course pretty expensive.
You'll need to choose between the 13 inch and the 15 inch model, with both offering various processor, storage and memory combinations.
The 15 inch Surface Book 2 provides 16GB of RAM and up to 1TB of storage for the highest spec machine. Additionally, it comes with a GTX 1060 chip with 6GB VRAM, so it is five times faster than the original Surface Book, Microsoft claim.
If a traditional laptop isn't for you, then the Surface Pro (2017) is a powerhouse tablet with attachable keyboard (although, you'll have to buy this separately). This tablet offers a Core i7-7660U, 16GB of RAM and a 512GB Samsung KUS040202M SSD. Its performance is very impressive, more than enough to run numerous business tasks.
Another one to consider is Microsoft's own Surface Laptop, which depending on the model, could set you back anywhere from £979 to £2,149.
Its cheapest model houses the Intel Core i5 processor, 4GB of RAM, and a 128GB SSD, while its top-end laptop comes with the Intel Core i7, 16GB of RAM and a 512GB SSD.
Finally, there's always the Surface Pro 4. It's not new, but it is still a solid machine. If you want to save a bit of money and still get a very capable machine, this is it.
Dell provides great business laptops, so you should definitely look at its Latitude and XPS range of powerful laptops.
From the Latitude line, we recommend Dell Latitude 13 7370. It is excellent, offering solid connectivity and an impressive battery life.
For those wanting to splash a bit more cash on a capable machine, the Dell XPS 15 is an excellent laptop with superb screen resolution and good battery power.
Apple MacBooks are portable and powerful but also expensive. However, there is arguably no nicer laptop for build quality. Plus, running Apple's macOS means you have less to worry about on the security front.
Essentially Apple offers four different laptop options: MacBook, MacBook Air, 13 inch MacBook Pro, and 15 inch MacBook Pro. But within that, there are more options to choose from, such as processor speed and storage allocation.
The MacBook Pro range spans two different scree sizes: 13 and 15 inch, as well as giving customers the option to forgo the new Touch Bar, which runs above the keyboard for key functions, in order to reduce the price of the 13 inch model.
The important thing to note here is that since Apple refreshed the MacBook Pro range in July 2018 these non-Touch Bar models haven't changed, while the other models have been enhanced with 8th-generation Coffee Lake processors, meaning blazing fast performance.
The Lenovo ThinkPad X1 Carbon is a very impressive laptop, and a stalwart for business use. It offers an excellent battery life, fantastic build quality, as well as being super lightweight and slim. It looks great.
It comes packed with a 2.7GHz Intel Core i7-7500U, 8GB of RAM, and lots of connectivity ports including three USB-C sockets, two USB 3.0s, a full-size HDMI and a miniature RJ45 networking port.
Another solid option is the Lenovo Yoga Book which is actually a tablet and laptop combined, which comes in just under £350. This beautiful laptop offers a portable but very usable screen, and a responsive stylus.
Finally, the touchscreen Lenovo Yoga 11 710 - thought to be a rival to the 12 inch MacBook - offers a 360-degree hinge and a capable eight-hour battery life.
If you're looking for a cheap MacBook alternative, then think Asus ZenBook UX305. This good-looking laptop is great for business users, offering a long battery life (10 hours), 8GB of RAM, 128GB of SSD and oodles of connectivity.
If you want to go even more budget, then the Asus Transformer Mini T102HA is one of the best value, low-cost laptops out there. For just over £300, you'll get a small and portable laptop with a sizeable hard drive and a solid battery life. It might not be the fastest machine, but it is nippy enough to complete everyday tasks most of us will encounter.
However, if money is no object then the ASUS ZenBook 3 Deluxe UX490UAR is impeccable. This premium laptop comes in at almost £1,700, offering 16GB of RAM, 512GB SSD, a 14 inch full-HD display and an Intel Core i7 (8th Gen) 8550U 1.8GHz Max Turbo 4GHz Quad Core Processor. This processor claims to provide 40 percent better performance than its rivals.
The Acer Swift 5 comes packed with an Intel Core i5-7200U processor, 8GB of RAM and 256GB SSD. Plus it's beautifully designed and is super slim, ideal for travelling.
Another excellent choice is the Acer Swift 3. This all-round laptop provides excellent build quality, good battery life and the performance will outrank many expensive laptops.
Many of HP's laptops will suit business users. They are normally well built and durable machines.
We like the HP Spectre 13 laptop. It's ultra-portable yet remarkably powerful, for a streamline laptop.
Using the Spectre is like using a MacBook, it feels premium and has features to match, offering an Intel Core i7-6500U (which is uncommon in thin laptops), a touchscreen, an 8-hour battery life and a good amount of ports for a super slim laptop.
Chromebooks are laptops that run Google's Chrome OS. In essence, they use Google Docs, Gmail and other Google tools instead of Windows or Mac software. You can use them when offline, but really they need a regular connection to the web to work. But Chromebooks are super cheap as well as stylish and powerful. And there are no real security worries.
If you're thinking of buying a Chromebook there are a few options worth considering. Dell offers a range of devices, including the Dell Chromebook 13 which has a long battery life. Alternatively, both Acer and Asus offer solid Chromebooks options for about £250.
And for those that want to take advantage of the Android OS and Google's Chrome OS, the Samsung Chromebook Pro is a solid choice, which includes a useful touchscreen feature.

9. Linux laptops
Another option is buying a laptop with Linux pre-installed on the device.
A quick search will find you multiple laptops from the likes of Lenovo, HP and Acer that run on a Linux OS. Linux OSes vary, but in general, the open source software is similar to Windows in look, feel and functionality.
There is no software license fee, so the same hardware is often cheaper running Linux than it is Windows or macOS. And you don't have the same security needs as you do in Windows. But compatibility is an issue, with both software and other devices.
