This is a good basic computer that will be fine for the average person's needs. The computer I was replacing was a Dell 2400, and it worked so well, I had it for years, and was quite happy with it. It still works, in fact, I just needed to let it RIP.
I've been using the 560 for about a month now, and have had no issues with it at all. My biggest challenge was familiarizing myself with Windows 7, as opposed to XP, and I like it.
The only thing I would do differently would be to have upgraded the processor (which the sales agent did suggest). The speed it runs is fine, but at times, could be faster.
I've had other brands in the past, and had nothing but problems. My last few computers have been Dells, and I would never consider anything else. The products are excellent, and the customer service has always been outstanding. I'm a customer for life.
