First, Determine What Your Precise Buying Factors Are
Are you using the Lenovo for coding, or are you using it for word processing? Are you using the Dell for gaming, for video editing, or for music mixing? Are you using whatever new computer you’re planning to buy for all those things and then some? If you just need a web portal, why spend $2k on the latest video processing device from some niche tech group?
Here we’ll cover a few notable factors that define Dell and Lenovo specifically, because they’ve got laptop options that are able to do all those things well.
Endless other brands are out there, but for most, these two are going to constitute the lion’s share of buying choices owing to affordability, operating systems, and availability. So with that in mind, the following factors will contribute to which of these you ultimately buy.

Exploring Dell Devices
Dell is an American company, and has devices across the board as regards availability. Cheap and expensive hardware is out there for you to choose from.
In general, today’s buyers are going to be looking for dual-core processors, which Dell provides. Screen sizes range from eleven to seventeen inches. Displays on Dells are notable, and have been compared to Apple devices.
In terms of graphical drive, you’ll find the AMD Radeon and NVIDIA graphics card options on varying devices. Battery life tends to be around seven hours on average. You’ll get better graphical capability, processing ability, battery, and speed with more expensive Dell devices; but you can find stripped-down basic models for cheap.
Exploring Lenovo
Lenovo is headquartered in China, and leans on Intel processors. Dual and quad-core processors are available based on how much the buyer is willing to spend. Lenovo leans on Intel graphics processors as well, such as the GeForce card. Screen size is variable, but Lenovo doesn’t tend to offer high resolution options. Battery tends to last five to ten hours.
On cheaper Lenovo devices, like those in the $250 to $400 range, battery life will be much shorter; expect two hours on some of the cheaper models. Also, Lenovo devices come prepackaged with a lot of software which many find convenient, but others find annoying.
Whenever you boot up, unless you disable such software, you’ve got to wade through notifications for five or ten minutes before you can do anything. For some, the information in these notifications makes this worth it. For others, it’s just a hassle. It can be deactivated, but if you’re not computer-savvy, that will be a chore.

Pros And Cons
Here’s a handy link that will put some notable pros and cons on display to help inform your decision. Generally, Dell tends to be a bit more established, technologically speaking. In terms of price and specification, they’re about the same—though Dell tends to have better battery life and screen design.
In terms of laptop range, you’ll find cheap, average, and high-end options in either category. All will be priced to compete with other laptop brands on the market. By many accounts, the big thing that’s a pro for one and a con for the other is customer service, which will almost always be superior on Dell’s side of the fence.
Reliability and customer assistance makes Dell the winner for many. Durability and cost-effectiveness leads others to Lenovo. Brand nationality is a third factor that decides the issue for some.
If this isn’t enough information to help you make a choice, then figure out specifications defining your minimum threshold of need, and compare associated pricing between options in Dell and Lenovo camps that fit your requirements.
Making Your Choice
Sit down and figure out what you expressly need. For most, that’s going to be the ability to watch movies, explore the web, play a few light games, and do some word processing. Others require video and sound editing capability. Still others need the laptop to code.
If you need something that’s a cut above the basic level, it’s wise to know that going in. Also, determine the way you’ll use the laptop. Lenovo has options where the “arrow” and “shift” or “enter” keys are oddly spaced, making word processing difficult. That can be a problem. Even so, generally, either device will serve the needs of users at all levels.
