I have a regular aspire that I've had for a little while now. I used to carry around a older inspiron 5100, but I grew tired of the weight and the poor design. It still ran like a champ, but the poor design prevents it from being on any surface that absorbs heat too much... like... a lap
Anyway, I still stand by my aspire. Have had zero problems. It's not the newer One model but it still weighs less than the Inspiron 5100 and has about double the battery life (about 2.5 hours/avg)
This is the one that it replaced
Dell Inspiron 5100
This looks exactly like it. It still runs but the hard drive just started to hiccup during spinups... I could've just replaced the drive, but I wanted to get something with internal Wi-Fi, weighs less than a mac truck and more than 32MB memory for video. (Yes the Inspiron 5100 is about 150 years old... lol .. seriously though, it's about 5 or 6 years old.)
So far I've had 4 different persons come up to me questioning why I would get an Acer laptop and actually depend on it. On all occasions I asked if they've ever used one and 1 person actually said that they used to use one for about 2 weeks from a friends inventory while the friend was trying another one out. The other people were basing their opinons on "The ratings and comments" that they found on the web somewhere. 2 of the 4 actually had the balls to base their opinions off of BestBuy (or the like) "Floor Models" LOL... anyway, I've actually used one for quite some time now and can honestly appreciate it. Doesn't belong to a company either. I treat it well, and it treats me well. Could weigh JUST a smidge less... but the battery life and the power are pay offs from the extra weight. And it still weighs less than the Inspiron. I know that the 5100 is an old model, but as for power notebooks that get knocked around... drop every now and again, I stand by it.
Again, it's not the "One" but if it comes down to trusting Acer as a brand... I would buy another one based on my own experience
