I'm using MBA mid 2009 (1.86GHz core2duo, 2GBs RAM) and everything seems fine with using Chrome open few tabs, facebook and iTunes. But it happens to lag when I tried to use Word, Excel, and the thing is my word file is almost nothing but text. I'm using SMC fan control and I notice that the temperature goes up 60-65 C when using Microsoft Office. Moreover, my MBA won't speed up when I quit MS word and it took me about 5-10mins for everything to come back to normal. So, should I switch to iWork?
