My 2008 MacBook is finally ready to give up the ghost. I'm debating between purchasing the new MacBook and a 13" MacBook Pro. I'm a lawyer, and I'm looking for a travel-friendly laptop that has enough juice to do some heavy multitasking for word processing and Internet usage (think like Citrix connectivity, 5-10 internet tabs open, multiple large word documents, lots of track changes, etc.). The new MacBook looks very enticing, but I'm concerned about whether the processor speed is going to be able to keep up with the demands I'm going to place on it. My wife has a MacBook Air and when I've used it I've noticed it can sometimes be a little slower in terms of handling multiple programs than I'd like. Anyone have any thoughts on the capability of the MacBook to handle heavy business use? The MBP 13" would obviously have enough power for what I need, but I wonder if it's going to be overkill and whether the laptop is too bulky for traveling. One extra note: I also have a work-issued laptop that is connected to an intranet but not the internet, so it is very possible that I'll be taking two laptops with me when I travel. Anyone have thoughts on traveling with a MBP? It could be that I need to get over my ambivalence with the MBA and accept that it is the best compromise solution (maybe the 11"?). But I was hoping to mine the collective wisdom of the forums. Thanks!
