Chip architecture, cache and bus speed are more important than raw ghz. 2 ghz is just a convenient benchmark.
The computers in smart phones probably beat anything sitting on a desktop 5-7 years ago, which all ran productivity software.
I'm sure my smart phone has more hardware than anything I used to run Win 3.1 on and it had Word, Excel and Lotus 123.
