My opinions and my own
At about 20-40 service calls per week, I have break-ups and love affairs with technology. Here are my current ones. (follow links for more info)

Loves
Laptops - Dell
Why? Easy access to hard drive, hardware failures pretty few and the Alienware Laptops just kick. Lenovo Laptops are pretty darn good too.

Flat Screen Monitors - Samsung
Why? Samsung makes great monitors. I sat in front of this 30 inch monitor last week for 2 hours and was in heaven.

Contact Management - BatchBlue
Why? I have migrated and we have cleaned up over 700 contacts this month with them. Pretty awesome service. www.batchblue.com

Computer Speakers - Bose
Why? I have never been a big Bose fan, but I heard these on a customers desk last month and the sound was amazing. He let me crank them up. Cool!

Blackberry Cover - OtterBox
I saw one this week on a customers Blackberry. Cool. Beefy, Rugged, very manly. But they have pretty ones too! I'm getting one! www.otterbox.com

Hates
Desktops - Compaq.
Why? They are cheap. Really cheap. Hardware issues abound. If you have one, please backup your data FREQUENTLY.

Hard Drives - Seagate 
Why? Many failures. Even their externals are having issues. See?

Anti- Virus - Norton & McAfee Security Suites
Why? They consume too many system resources. They're Pigs.
