Just bought a cheap Asus 14" notebook... As an entry level notebook I threw a 120GB Patriot SSD and 2 x 4GB RAM in it... Boot time without Asus bloatware is 45sec... With all the software I want on it the boot time is 55sec... With antivirus it pushes the boot time to over a minute...
Still very good considering those entry level notebooks take so long to boot you go make a cup of coffee while you're waiting...
Playing video files is super quick, no delay from clicking the file to the player playing the video... Previously there would be a 5+sec delay with the timer going while the HDD churns away...
There's no noise because there's no moving parts and it runs cool. So expect better battery performance...
MSY is the best place for components... I got a Sata III drive just to future proof it... Sata II 128GB drives are $60 - Insane!
A $60 SSD and an increase of RAM to 4 or 8 GB will do your lappie wonders...
