Don't forget malwarebytes.org for their superior malware scanner. I also like AVG for antivirus.
Yeah, the new Mac laptops with the corei5 and corei7 processors looks nice but I'm a bit broke at the moment.
I prefer Lenovo/IBM over Dell - the IBM T42 the company gave me ran for 3 years with it running 5 days a week bouncing around in the back of a car and never had a problem. The Dell Latitude D630 on the other hand that they replaced it with was faster but has been thru 3 motherboards, 3 hard drives and 3 cooling fans.
Kind of a lemon if you ask me. Warranty is up in December, hope they replace it before it disintegrates altogether.
