Dells are great. and they are very reliable. we have about 600 of them at work. things change in the technology world, though, but I wouldn't go with acer. I would consider MPC. they have these great all-in-one desktops now . . .
I was thinking that too originally. Consumer Reports had recommended some of Acer's computers and I didn't have much trouble getting through to Acer's customer service. I don't believe Acer's customer service is 24/7 like Dell.
I took a look at the Acer Aspire One at a local Radio Shack and in addition to their battery being longer, I liked the keyboard better than the Dell. Some of the Dell's keys are sized smaller and placed differently than usual Qwerty keyboard.
I took a bit of a chance, but it looked like I would be getting a bigger bang for my buck. I was disappointed that some of the features on the Dell Mini 9 was not on the same level as the Acer Aspire. I should be getting it shipped to me this week. I hope I made the right decision. I will provide a review if anyone is interested.
I will be in the market for another desktop and I'm sure it will be a Dell.
