Could replace my 15" Alu
Authored by: frenchfries on Jan 15, '08 07:50:25PM

I'm working on 3.5 years on my 15" 1.5 GHz, and I'd love to have a dual core book. Based on my experience with my quad G5, for a lot of what I do the multicores work really well. I would love to have an intel Mac so that I can use Fusion/Parallels. I know that 2 GB is sufficient memory--I have 8 GB on my quad and that is only taxed when my students do heavy calculations. One negative is the small 80 GB disk, but I just bought a 120 GB LaCie little disk, and it can be bus powered. I'm hoping that the USB port on the Air has enough juice to power the disk, my powerbook requires a powered hub to run the drive (or plugging in the auxiliary USB cable to my second USB port). Another negative is the lack of FireWire. I'm thinking that this means I have hold on to my Powerbook for its FireWire port so that I can still use my video camera.

Basically, there must be compromises made to reduce the size of the machine, and I would love to have a 3 lb computer that is actually up to more than twice the speed of my current laptop. The small size really is significant. I'm wondering whether there is any point in not getting the 1.8 GHz model. With my edu discount, I can get it less than $2K.

One last thing I haven't heard, but on Ebay you can get USB ethernet adapters for $2, so there is probably no need to pay $30 for Apple's adapter. Also, I can mount DVDs from another computer right now, so I agree with Apple, there is really no need for a built-in device. I almost never use the DVD drive on my powerbook, but I will when I need to install software on the Air. I imagine there are a lot of folks who can't tolerate the performance and port limitations, but I have the luxury of several machines for that.
