Hi Folks,

So I installed kali linux 2.0 rolling on my 2007 Dell Inspiron 1420 (Core 2 Duo 1.5GHz, 2GB RAM)

Somehow it works okay, but not fast. Applications like FirefoxESR and booting takes **** lot of time.

Do I need some better specs laptop?
Or I can just upgrade HDD to SSD and RAM to 4GB?

I'm thinking of getting a refurbished Lenovo Thinkpad X230
or a Lenovo Thinkpad E450

The machine sole purpose will be to use Kali linux for pentesting along side windows 7

Any suggestions would be highly appreciated.

Thanks and cheers!
