Bought this Lenovo almost a month ago... i've installed all the softwares that i had in the older Sony Vaio, till now, very smooth, very responsive, no hiccups... just that i haven't figured out how to use the entire 500 GB HDD, as i was able to installed Win 7 Home Basic and only am able to use around 390 GB of it...!!! everything else is smooth sailing. execution of programs, multiple browsers and then multiple browser windows and tabs... all are smooth till now... startup and shut down are faster as well... haven't tried any gaming on this but i guess if my 5 years old Sony VAIO can handle it so can this one.. btw i only play FIFA 12 and it runs just fine in SONY... thought i'd keep this one for work only...!!!
