DVD Drives: Most come without a DVD drive now, as most software, music, video, etc. These are becoming more of a rarity these days as laptops/notebooks become thinner and lighter. Wired: Aside from the ubiquitous Wi-fi connectivity, if you prefer to use a faster-wired connection while in the office, you will need an ethernet port. Options such as fingerprint readers, ruggedization for adverse conditions, etc. If you need more disk storage space you may consider getting an external hard drive. SSD drives also have much less capacity than HDD drives. Disk speed: Solid state drives (SSDs) can give a huge performance boost over the traditional mechanical hard drives (HDDs). SSDs are more expensive than HDDs but are rapidly declining in price. For power users or gamers, 16 GB or more may be required. If you intend to run multiple applications simultaneously, more is preferable. Amount of memory (RAM): A typical inexpensive laptop/notebook comes with 8 GB of RAM which is sufficient for light duties.
Graphics (GPU): If you plan to run graphics-intensive gaming or virtual reality (VR) applications, a high-end graphics processor is essential. Ultra high-end graphics capability can easily add over $1000 to the price of a laptop.If your tasks mainly involve word processing and web surfing, you won't need a faster processor. Processor (CPU): Pricier models have higher processor speeds, which means better performance with CPU intensive tasks.
