I'm a travel photographer and would like to shrink the poundage of my electronic devices. But I also need to be able to perform some advanced/memory-intensive functions in photoshop, such as working with large RAW files, splicing panoramic images, etc. Can anyone give an educated guess if the new MBA coming out this month will be able to handle these kind of memory/processor-heavy tasks with reasonable performance? (Assuming that the new MBA will have SandyBridge with the integrated graphics card, Thunderbolt, etc.) Or do you think it will just hang with only 4MB memory? Anyone have experience using "heavy" photoshop tasks (RAW images, etc.) with the current MBA? How is the performance? Does SS memory and drive help compensate for the low memory and slower processor? Thanks!
