I have been lurking here for the past few years and bit my tongue during the first round of ultraportable comments here on MacRumors. I decided I needed to register to get into the fray here. Here goes, my first post... and it's a long one...
First- who wants an ultraportable Mac? Many people! My laptop history:
IBM ThinkPad 701C (Butterfly keyboard)
Toshiba 320CT
IBM X23, X24, and X31
Toshiba M200
Fujitsu P1610
12 years of carrying laptops on the road. What do all of these have in common? A screen from 8.9" to 12" diagonal, and NO optical drive. My current laptop, the P1610 has been upgraded by me to use a 32GB SSD, and the speed/battery life boost was well worth the $500 extra dollars I paid at the time.
Regarding SSDs:
I'm sure Apple has a bit of leverage in the NAND market, and will get their SSDs for less than the average Joe can pick one up on Newegg.com. Not that they will pass the savings along to us. Expect a low end model to have a standard 1.8" 80/160GB iPod hard drive. Anyone looking for performance will skip this and take an SSD.
Regarding Touch/Multi-Touch:
Apple will not bring out a touch screen of any kind on the ultaportable. OSX user interface elements will be too small to interact with using a finger on a screen 13.3" or smaller. Small possibility that they could incorporate a Wacom digitizer and pen, but the odds of that are so remote that they're not worth considering.
Regarding Specs:
13.3" is not a true "ultraportable" in my book, or anyone else who has used true ultraportables (see Dynamism.com for good examples, or the Fujitsu P1610). If that screen size rumored is correct this should fall into the "Thin and Light" category. An ultraportable should not only be 3lbs or less, the screen should be 12" or less diagonally. Finally, smaller laptops are not specifically excluded from having dedicated graphics (Look up notebooks from LG for examples of small laptops with GeForce integrated).
Assumptions if the screen is 13.3"
-------------------------------------
Core 2 Duo processor at 2.0 to 2.4GHz
Up to 4GB of RAM
GeForce dedicated graphics with 128MB SDRAM
Screen resolution probably 1280x800, small chance of 1440x900.
Assumptions if the screen is 11.1" to 12.1"
----------------------------------------------
ULV Core 2 Duo processor at 1.2 to 1.6GHz
Up to 2GB of RAM
Previous generation GeForce dedicated with 64-128MB SDRAM
Screen resolution probably 1280x800, small chance of 1366x768 (11.1" screen from Sony TZ series).
The Other specs
------------------
Gigabit Ethernet
802.11n Wifi
Bluetooth
2MP iSight Camera
2 USB Ports
1 Firewire 800
HDMI video output (with DVI conversion adaptor)
OSX Leopard
External optical drive (possibly bundled, likely purchase separately)
Regarding Price:
Apple is not known for low price, but for high quality at an average or slightly high price. Do not expect an "ultraportable" to cost $999, no matter what company produces it. My educated guesstimates from past experience would be as follows:
Mac Ultraportable with 80GB 1.8" standard HDD, 1GB of RAM --- $1699
Mac Ultraportable with 32GB SSD, 2GB of RAM ---------------- $1999
Mac Ultraportable with 64GB SSD, 4GB of RAM ---------------- $2999
If we are lucky they will throw in a USB powered external SuperDrive (clad in aluminum as well). Otherwise expect that to be $299 extra.
OK, the show's over now. I use Windows based laptops for work/travel and an iMac at home. I want to switch over completely (and use Parallels / VMWare Fusion for work). Almost did when the MacBook line came out, but it's size/weight/plasic turned me off. This rumored upcoming model should be just about right. I'll buy one even if the screen is 13.3", but will probably buy a round for the entire office if they make it 12" or smaller!
