I'm in the market for a new laptop. It would also replace my Mini as my main computer. The MacBook Pro would probably be best, but I also like the new MacBooks. As I am a translator, I use my computer a lot with CAT-tools (Computer Aided Translation), especially Wordfast Pro. I also always have a dictionary, a browser and my e-mail open. These programs use a lot of memory and large translation memories. My current Mini (late 2012, 2,5 Ghz, 4 GB) occasionally has a hard time dealing with this. From time to time, I type faster than the letters appear on my screen. What should I look for in a new computer? I guess memory and processor speed, or am I overlooking something? I suppose 8 GB will be better than 4 GB, but what about the processor? Can a MacBook deal with CAT-tools? Any tips would be appreciated.
