Laptops, What would you suggest???

i guess it's time to live in the 21st century... i have to get a laptop, but having various brands out there such as dell, sony vaio, ibm lenovo, toshiba, fujitsu siemens, apple, hp, acer, compaq, averatec, asus, alienware, emachine, gateway, panasonic, samsung, LG, sharp, sager and others, doesn't make it easier to decide!!!

Anyway, according to the offers i got from our "beloved" jordanian market, my choices currently are:
1- HP Pavilion dv5278
2- Toshiba Satellite M100-222
3- Apple MacBook Pro (MA464LL/A)

Since am intending to buy 1 that is supposed to last for a very loooong term, i'd like to get all the computer power i can afford. it'll be used for long hours, heavy duty (image processing and similar stuff), which means that i'll be needing a reliable laptop with atleast 2 GHz Intel Core 2 Duo processor, 2 MB cache, 1GB DDR2 RAM, 100GB high performance HDD, long battery life, and does not weight more than 2.5 kg, with a budget that nearly does not exceed 1500JDs)

HP meets all the above, except for it's weight and size, which is a very important issue since i move a lot (but hey, it's just an extra .5 kilo afterall!)

Toshiba has much much better specs, it also weights less (the price is 150 jds more than the HP, and i believe it's worth it ;) but nothing is perfect... it has a very low battery life, and i don't think i'd like it if the battery decides to die while am in the middle of smth, and couldn't find a near by AC source... i hate recharging batteries!

Mac is just great, and i know it can boot from either Mac OS X or Windows XP, but i still donno how compatible it is with the available softwares in the market, and i still donno how much it's gonna cost...

So, experts out there and laptop owners, i really would appreciate it if you'd kindly give me your opinion :) thanks in advance!

p.s: i know that some have already asked me to get a dell or a sony vaio, but the offers i got weren't that great (either low speed or too expensive to get)
