Macbook Air (2011) and Lightroom

I am planning on replacing my dell laptop with a 2011 Macbook Air 13in with i7 processor. Will this computer run Lightroom 3 well? I don't do much editing outside of lightroom, so i don't think i will need a powerhouse computer either.

My current laptop runs lightroom 3 well, but sometimes rendering could be a bit laggy. it is a 2008 Dell xps 1530 at 2.4ghz and 4gb ram ddr2 and 7200rpm hdd.

I am planning to give my mom this laptop since her's is starting to die. And I want a very lightweight laptop for class, but powerful enough to be able to run lightroom (probably the one of the most demanding tasks i'll be doing).

It will be a lot faster than your old Dell, but I think you will find it's and i5, not and i7

But, it will still lag when rendering previews, importing and working with the adjustment brush.
I use a faster version of the i5 in a laptop for tethered shooting, but still find I need my desktop for serious editing.

But for working in Library mode and basic editing, it will be a lot faster than your old Core 2 based computer

If you switch to Aperture it will be much faster than Lightroom because Aperture uses the HD3000 gnu for many of its tasks.

i use a MBP with a 2.4 ghz i5 and 4gb of ram. runs lightroom perfectly doesnt lag atal. only time it does is if ive got PS and itunes open aswell.. Just about to upgrade to 8gb as its come down in price loads..cant wait too see what its like then!

There is a i7 version.

I have this with LR3.

Works well.

I also have a desktop with Q6600, SSD (for OS and programs), HDD (for pictures), 4Gb RAM. The 13" MacAir previews and renders much faster using mRAW files from a 1D mark IV.

I'm not using PS nor iTunes in the background.

It's great for portability on the road. Satisfied with my purchase
