I mean picture the average businessperson or college student moving from location to location. Do they really need a five lb. laptop that can compete against supermodels? I mean you're going to have to carry other things anyways, and the extra weight can be good excersize :P
It just doesn't seem right in any way for people to sacrifice processing power for a few pounds. Why would anyone buy a macbook air when they could get a comparably priced macbook pro? It's not like portability matters that much for five lbs. I've never found it difficult to carry my laptop to the library this summer.
To quote:MacBook Air vs. the MacBook & MacBook Pro : Ben Patterson : Yahoo! Tech
Size/Weight: 15.4-inch screen, 5.4 pounds; 17-inch screen, 6.8 pounds
Processor: 2.2-2.6GHz Intel Core 2 Duo
Storage: 120-250GB hard drive
Optical drive: Combo or SuperDrive
Graphics: NVIDIA GeForce 8600M GT processor, 128-256MB of dedicated memory
Ports: DVI, FireWire 400 (1), FireWire 800 (1), USB 2.0 (2-3), headphone out, Ethernet, ExpressCard slot
Wireless: Wi-Fi, Bluetooth
Base prices: $1,999 (15-inch 2.2GHz, 120GB HDD), $2,499 (15-inch 2.4GHz, 160GB HDD), $2.799 (17-inch 2.4GHz, 160GB HDD)
Pros: Fast Intel Core 2 Duo processors, up to 2.6GHz; dedicated NVIDIA graphics processors for speedy graphics performance and external monitor mirroring at high resolutions; ExpressCard slot for wireless broadband cards; plenty of ports, including two to three USB 2.0 and FireWire 800; backlit keyboard.
Cons: Heaviest of the Apple notebooks, especially the 6.8-pound 17-inch model; pricey.
Who it's for: Business users and pro-level image and video editors who need speedy mobile performance; on-the-go gamers who demand smooth 3-D graphics.
Who it's not for: Casual users, non-gamers, anyone who's never fired up Final Cut Pro or Photoshop; on-the-go types looking for a light load (especially when it comes to the 17-inch MacBook Pro).
Just announced, and thus still untested by reviewers, this whisper-thin notebook was the big news at Macworld last week, and at just 0.76-inches thick (at its thickest point) and weighing in at a mere 3 pounds, it's one of the sexiest notebooks I've ever laid eyes on. That said, the Air's slim good looks come saddled with some serious compromises.
Size/Weight: 13.3-inch screen, 3 pounds
Processor: 1.6-1.8GHz Intel Core 2 Duo
Storage: 80GB hard drive, 64GB solid-state drive
Optical drive: none ($99 external drive available)
Graphics: Intel GMA X3100 processor (integrated)
Ports: Mini-DVI, USB 2.0 (just one), headphone out; no FireWire or Ethernet ports (USB Ethernet adapter available)
Wireless: Wi-Fi, Bluetooth
Base prices: $1,799 (1.6GHz, 80GB HDD), $3,098 (1.8GHz, 64GB solid-state drive)
Pros: Super light and thin; guaranteed to make friends and neighbors green-eyed with envy; full-sized, backlit keypad; multi-touch track pad; solid-state drive makes for lightening-fast data access.
Cons: Test results aren't in yet, but the Air's specs point toward slower processor speeds compared to the MacBook and MacBook Pro; no dedicated graphics card (similar to the MacBook); no built-in Ethernet; only one USB 2.0 port; battery is sealed in the casing; no built-in optical drive (although the Air can wirelessly share the optical drive on another Mac or PC); no ExpressCard slot for 3G broadband cards; the solid-state drive-equipped Air is hideously expensive.
Who it's for: Good question, actually. My best guess, for now: Apple fanatics who must have the latest hardware; style mavens who love droll-worthy tech; road warriors with deep pockets who need the lightest possible laptop (and who, ideally, have another system back at the office).
Who it's not for: Video editors, gamers, or anyone else who might need speedy processing power; bargain hunters; road warriors who depend on 3G networks for data; jet-setters who need to swap out the battery."
