Best Business Laptop

                                        Lenovo ThinkPad T450s

With its 2.3-GHz Intel Core i5-5300U, 8GB of RAM and 256GB SSD, our configuration of the ThinkPad T450s was more than powerful enough to handle any productivity task. On Geekbench 3, a synthetic benchmark that measures overall performance, the T450s scored 5,993. That's below the 7,082 thin-and-light notebook category average but on par with similarly specced systems like the ThinkPad X1 Carbon. The MacBook Pro 13-inch and its 2.7-GHz Core i5-5257U were noticeably faster.
                          

Ideal for office work, the ThinkPad T450s took just 4 minutes and 41 seconds to complete the Laptop Mag Spreadsheet Macro test, which involves matching 20,000 names with their addresses in OpenOffice Calc. That's a minute faster than the category average (5:41) and 33 seconds quicker than the T440s (5:14). The MacBook Pro fared better, finishing in just 3:28.

Because of its speedy 256GB Toshiba SSD, the T450s finished the Laptop Mag File Transfer test in just 34 seconds. That's a rate of 149.7 MBps, about 40 percent above the 104.2 MBps category average but not quite as fast as the MacBook Pro, which notched a rate of 386 MBps.
