Yes, Steve Jobs is counting on the 'halo' effect to revive Apple computer sales.
Note, however, that you can hook an Ipod to any IBM notebook with the proper connection ports and HP even sales an Ipod version with a 1 year PC support warranty for the Ipod (Apple gives 90 days for its version but either one will work with either notebook).
But Apple is #1 in reliability and service so they are a great choice if you can live with a non IBM standard notebook.
The only way you can get a decent 15" or 17" LCD is with an IBM Powerbook. Also, they have dedicated video (built in video card up to 64mb at least)for gaming and higher end video (and you want this if you will be doing video editing).
The Ibooks are great for travel and general use but their LCD size and keyboard size is too small for everyday use and I don't know if they have dedicated video either (if it says shared or integrated video there is no video card).
So, for the $2,000-$2500 range (depending on whether you get the combo drive or DVD burner superdrive) the 15" Apple powerbook is your best size and performance notebook.
Note that the 17" Apple powerbook at 6.9 pounds and $2800 is an incredibly low weight for that LCD size but that size will not fit in a notebook backpack for travel. But the LCD is gourgeous so if you will mostly use it at home and can afford it consider this one also.
I have decided to get a Mac laptop, but I am confused as to what one to get? I hear either one would work with the multimedia type projects I want to work on. I want something I can travel with, watch movies on etc. I just got an ipod for christmas and love it and would like to connect that and a digital camcorder to the laptop. Finally, what size screen should I get? Any help would be appreciated. Thanks.
