How to Buy a Laptop #3

Optical and other drives: Most manufacturers offer laptops with rewritable DVD drives. But now that Blu-ray Disc has triumphed over HD DVD in the high-definition format wars, more notebooks are being configured with Blu-ray drives. If you need a floppy drive for some reason, you can buy a USB add-on drive for 20 bucks.

Hard drive: Even inexpensive netbooks now come with 60GB hard-disk drives (HDDs). Most all-purpose machines offer hard drives in the range of 200GB to 320GB, and ultraportables now pack solid-state drives (SDDs). Though SDDs are faster and lighter than HDDs, their capacities are considerably lower (maxing out at around 128GB) at a significantly higher cost. In today's market, an SSD adds about $1,000 to a laptop's price tag over the cost of a machine with similar specs equipped with a larger-capacity platter-based drive. So, you need to balance speed and weight against price and storage capacity. Whichever choice you make, you'll find that hard-drive space fills up quickly, so you might want to consider buying a portable external drive as well.

Weight and bay design: Laptops range from 15-pound desktop replacement monsters to ultraportable lightweights that rely on external drives to come in at under 3 pounds. One-bay notebooks balance features and weight. Some laptops continue to offer the optical drive as a modular device, so you can swap it out for a second hard drive or a second battery.
When making a purchase, however, keep in mind that you should consider the weight not only of the laptop but also of the AC adapter, the extra batteries, any external modules, and their cables. Ultraportable notebooks have lightweight adapters, but they can weigh almost as much as a full-size notebook if you have to carry an external optical drive, too.

When you return to your desk, you can snap most laptops onto an extra-cost docking station or port replicator (prices range from $100 to $500). Doing so saves you from repeatedly having to plug in and unplug an external monitor, keyboard, mouse and other desktop peripherals.
Communications: Few laptops come with a full set of legacy ports anymore. Serial ports are as rare as Bigfoot sightings at this point, as are PS/2 ports (for a mouse or keyboard). Most notebooks still have one PC Card slot, though many now offer an ExpressCard slot as well. With new GPUs, many notebooks -- and even some netbooks -- now offer HDMI outputs.
Most laptops have at least two USB 2.0 ports; many offer four, and some up to six. A majority of notebooks include a four-pin FireWire (IEEE 1394) port for connecting an external drive or a digital-video camcorder. Others now include eSATA ports for high-speed data transfers.
Built-in Ethernet now comes standard on all portables, with many models carrying gigabit Ethernet. Many laptops also have built-in Bluetooth. Notebooks using the Intel Core Duo or Core 2 Duo processors -- or AMD's Turion 64 X2 processor -- include Intel's wireless 802.11a/b/g chip set.

Some laptops come with built-in wireless broadband wide-area networking, enabling them to access, for example, Verizon Wireless's EvDO Broadband Access service.
Most also include a multiformat flash card reader, which can read Secure Digital, MultiMediaCard, Memory Stick, Memory Stick Duo and xD formats.
