As fate would have it, an Intel chipset glitch delayed shipments of almost every laptop manufacturer, save one.Akku Compaq Presario CQ60 Apple, which has typically been last in transitioning to new technology, is now among the first to launch laptops with Sandy Bridge (known officially as second-generation Core CPUs)—and arriving first has its privileges.Akku HP Compaq 6710b The Apple MacBook Pro 15-inch (Thunderbolt) ($2,199 direct) is the fastest laptop on our bench, thanks to a component overhaul that involves the first ever quad-core processor on a Mac laptop and a rekindled romance with AMD graphics. And then there's Thunderbolt, a new connection technology that has mounds of potential, but I'll contain my excitement until compatible peripherals ship. This, and a new Facetime HD Webcam, places the MacBook Pro 15-inch (Thunderbolt) at the peak of technology's Mount Olympus and earns it an Editor's Choice in the desktop replacement laptop category.

Thunderbolt Icon Is the only Design Change
Design-wise, don't expect a thinner or lighter laptop. The only change to the design is the addition of a Thunderbolt icon next to mini-Displayport. The MacBook Pro 15-inch (Thunderbolt) keeps its wondrous shape and form, since all of the changes are from within. At the moment, I don't see a need to alter its exterior. It's still the thinnest, most streamlined laptop in its class,Akku HP Pavilion dv9000 made so by carving the center out of a thin slab of aluminum. It's at least a quarter of an inch thinner and about a pound lighter, at 5.5 pounds, than the Dell XPS 15 ($1,115 direct, 4.5 stars) (6.3 lbs) and Asus N53JF-XE1 ($1,015 street, 4 stars) (6.3 lbs).

The MacBook Pro15-inch (Thunderbolt) has several screen options,Akku HP Compaq nx7400 all of which require that you pay a significant premium, although I can't think of many consumer laptops that have an anti-glare screen (a $150 option). There are laptops that can scale to higher resolutions, though. The XPS 15 and the N53JF-XE1 either ship or have an option for a 1080p display (1,920-by-1,080);Akku HP Pavilion dv6000 the Macbook Pro 15-inch is available with a 1,440-by-900 or 1,680-by-1,050 display ($100). Still, having screen options is a luxury that few others are willing to offer. The HP Pavilion dv7-4283cl, for instance, is only available with a glossy screen and 1,600-by-900 resolution.

The chiclet-style keyboard carries on the Macbook Pro tradition of black keys that matches the black of the screen's bezel.Akku HP Pavilion dv2000 Backlights, which are found between the keys and aluminum foundation, are absolutely invaluable in low-lit situations. You can also find a backlit keyboard in the XPS 15. The signature Apple clickpad dwarfs all others in terms of size and responsiveness.Akku HP COMPAQ Business Notebook 6820s No other touchpad can recognize two- to four-finger gestures as accurately and fluidly as Apple's, and the reason for this is two-fold: First, it's made of glass, which doesn't wear out over time. Others use acrylic or some lesser material in their touchpad construction. Second,Akku HP ProBook 4510s the coding drivers and software for the touchpad are created in-house (instead of through some third-party developer) so that each click, swipe, or pinch works to perfection.

What is Thunderbolt?
The last time Apple led the way with a new connection technology was when it initiated the FireWire standard. Thunderbolt,Akku HP ProBook 4515s an I/O technology from Intel (codenamed Light Peak), operates under a similar principle in that it boosts transfer rates to unprecedented levels. The technology lives inside the mini-Displayport, so structurally the port looks exactly like the one in the previous MacBook Pro iterations. But when it's connected to a Thunderbolt-equipped peripheral, transfer rates can hit a theoretical 10Gbps.Akku HP ProBook 4520s That's roughly 21 times the speed of USB 2.0 and FireWire 400, 12 times that of Firewire 800, and twice that of USB 3.0.

The Thunderbolt port, as Apple explains it, is essentially taking PCI Express—the channel that every port and slot goes through—out of the box. It's like finding the shortcut that gets you directly onto the five-lane highway.Akku HP ProBook 4710s Originally, Intel designed Thunderbolt to work over an optical cable, but because it has yet to figure out how to power external peripherals through this method, copper is used instead. You'll need a new cable that runs from the Thunderbolt/mini-Displayport to the external device.Akku HP ProBook 4720s Yes, it can still output to an external display—or connect to any device for that matter. As proof, Apple demonstrated a RAID server (made by Promise Technologies) attached to the laptop, which was then attached to an Apple Cinema Display,Akku HP Pavilion dv6500t in a daisy chain configuration. Thunderbolt is bi-directional, meaning it can have two streams going at the same time—up to 10Gbps for each stream. In practice, for instance, you can simultaneously stream four uncompressed 1080p video clips from the RAID server to the laptop (first stream) and then display out to the Cinema Display at the same time (second stream) without lag or distortion.Akku HP Pavilion dv6500z You can barely stream one uncompressed 1080p clip through FireWire, let alone four. During Apple's demonstration, transfer speeds were peaking at 5Gbps—the realistic speed of Thunderbolt, judging by the throughput meter Apple had in place.

You can also think of Thunderbolt as a universal port. If a company were to create a Thunderbolt hub or adapter,Akku HP EliteBook 2530p it can work with all sorts of connection technologies, including FireWire, USB 2.0, USB 3.0, eSATA, and Gigabit Ethernet. Remember, all of these technologies go through PCI Express at some point. Before you get too excited,Akku HP EliteBook 2540p though, Thunderbolt peripherals won't ship for months (the ones that were on display were prototypes), and Apple is rumored to have an exclusive on this technology until 2012. So doubts about its adoption rate is completely understandable.Akku HP COMPAQ 2400 Update: Intel pointed out that there is no exclusivity on Thunderbolt, OEMs are free to implement it when they think the time is right.)

Facetime HD and Usual Suspects of Features
With the new HD Webcam sensor,Akku HP Notebook 2510p video feeds no longer look grainy or grotesquely stretched when filling the entire screen. The streams are broadcast at a resolution of 1,280-by-720 (720p), which is about 3 times the resolution of the Webcam in previous MacBook Pro models. Video chatting with the Facetime app, over a Wi-Fi connection,Akku HP Compaq 6510b was free of distortions. The MacBook Pro 15-inch (Thunderbolt) isn't the only laptop with an HD Webcam, though. You can find one in the Dell XPS 15, which has a Skype-certified HD Webcam. Lenovo, Sony,Akku HP Compaq 6515b and HP have also rolled out laptops with 720p-capable HD Webcams.

Every other port and slot remains untouched from the previous iteration. It has two USB ports,Akku HP Compaq 6710s FireWire 800, a Gigabit Ethernet port, and SDXC media card slot. The dual-layer DVD burner will seem generic compared with the Blu-Ray drives found in the Dell XPS 15 and HP Pavilion dv7-4283cl ($999.99 list, 4 stars).Akku HP Compaq 6715b And don't expect to see a Blu-ray drive in a Mac laptop anytime soon, as this is a road Apple so far refuses to take. This configuration ships with a 750GB hard drive that spins at 5400rpm; the Dell XPS 15 and HP dv7-4283cl come with faster 7200rpm drives. The MacBook Pro 15-inch (Thunderbolt) offers SSD drives as well, in 128GB ($100), 256GB ($500), and 512GB ($1,100) capacities.
