Comment system=all components+OS (Score 1) 501
I've had quite a few desktops and laptops in my life. After a while I decided that building my own desktop only led to problems from specific incompatibilities. Most software is going to be tested on a well sold Dell model.
I don't know about build quality of the exact specs on every component but I know this:
My Toshiba laptop's screen was dead after 1 year. Most other workers who had one also died within 2 years.
My Dell's screen was OK but the sound card was terrible; you could hear the HD spinning. Also I really hated XP vs OSX
I currently have another Dell which has OK screen and sound but all colors on the screen are very cold vs normal LCD. Works pretty well with Windows 7.
As for my own money. I have a 4 year old Mac mini who is now a DLNA server for my PS3 and iTunes server also. Works amazingly well and dead silent.
I have a macbook pro and so does my wife. They work perfectly and have great screens and soundcards.
I also use an iPhone 3GS which work well enough that I don't want a 4. My kids watch movies on netflix ipod touch.
My experience with Toshiba,Dell and Apple products tell me one thing. Buy Apple again. the margin might be thinner now that windows 7 is here because it is pretty good. I would say that a current Dell with a good LCD panel with good colors and windows 7 would probably do the job just as well.
Then there are the little things like time machine. configure it once on the wife's computer and never worry again about forgetting to click on the backup icon.
