I am not a fan of companies, only products. I don't buy a company, I buy a device.
That being said, the devices I am most impressed with, both for value and quality, are my Apple products.
In our home, we have 2 Mac laptops (a 17" Mac Book Pro, and a White Mac Book), two 3G iPhones, and iPod Nano, and a 5th Gen iPod.
All the devices have always worked flawlessly. The products, for what they are, are very cost effective. My MBP is coming up on 3 years old. The only other laptop at the time that could come close to it's performance, was a Dell, and it cost $600 more. The only time I have messed with the OS is to upgrade Tiger to Leopard. I am a device geek, and have had no desire to upgrade my laptop. It runs as well today as it did the day I bought it. When Snow Leopard comes out, it will run even better. WHen do you ever see an OS go through two versions, only to preform better on three year old hardware.
It's akin to Windows 7 running better on older hardware then XP.
The iPhone has been an incredible device as well. Just the other day, I was looking for a Camera that will geoTag my pictures. The best solution I came across, was a $120 thing that you put the memory card into, and it add the geo locations to the images.
I got to thinking... my phone has GPS, I wounder if there is an app on the app store to do this. 3 minutes and 4 dollars later, I had it. WIth 30,000 apps all in one place, it's like nothing else on the market right now.
I have 5 pages of apps on my phone. Everything from weather with animated radar and video, to geotaging, to barcode readers, to twitter, Shazam, Pandora, music, movies, photos, sports information, file sharing app, a dozen games... the list goes on. It's an amazing appliance.
I also have 5 PC's, and for what I want them for, they are the best solution.
