Summary: I've been a Lenovo T-series user for about a decade, going through 4 T-series laptops for work. I finally bought a personal laptop for myself, because the soon-to-be released T440 is trying to be something it's not, which is an ultrabook (no more ultrabay, touch screen, internal battery). So I thought the T430 would be the last of it's kind for traditionalists who like Windows 7 better than 8, and like that this laptop can be upgraded with a 2nd hard drive, etc.
Summary: Performance: -I use this laptop for work and it is not the best productivity machine. 4 gbs of ram is fine if your intended use is casual, however having multiple spreadsheets open while running Adobe reader, IE and various other applications can easily leave you spending a frustrating amount of time waiting for process to run.
