I ordered this Ultrabook a few weeks ago and received it on Thursday and I must say it was exactly what I hoped it would be. I currently have a HP Elitebook 8440w which was around $1600+ and my wife has a Macbook Pro and the new Mac Air.
I am very disappointed with the HP, slow, bad keyboard, not stylish, and wanted a slim, sexy laptop with long battery life but one that also has an optical drive (yes, it has been a while since I last used it but I miss it when it is not there)and although my wife wants me to get a Mac I was looking for a Windows based system.
Then I saw a review online about this Acer M5 and it was giving it high praises and firmly recommended it. I was worried that it would be a cheap machine and was not very familiar with ACER but the video in the review showed the product clearly and I bought it at Amazon.

OK, the product looks very nice, it might not have the metal housing of a Mac but there is zero flex with the screen, the keyboard or the body in general. The screen is big but very thin and the graphics are great. The touch pad is huge but I feel that it could be more responsive but I have not yet fiddled with the settings. I read the review about the keyboard and was surprised. It looks like an Apple Air keyboard, the chiclet style, only that the individual keys are slightly further apart. After the first few hours of typing I had no complaints and the back-lit option is great!
The power key is at the front, and yes, this might not be ideal but as it is below the edge it is not actually sticking out and for somebody to accidentally push it, well, I will try it but it seems rather unusual that this could happen unless you try to throw the laptop like a discus at the Olympics.

I am a certified computer tech and I have lots of experience with gadgets and computers. I replaced a 5 year old sony viao laptop with the acer aspire timeline U because of the specs of the machine. I was looking for a lightweight computer with a dvd drive and the abiity to play computer games such as Portotype 2 and Skyrim. There are areas where compromises must be made in order to save weight and cost. These cuts are ususally in the optical drive and a powerful video card.

First of all, I think the keyboard is perfectly fine. It is backlit and I have not had any problems typing on it. It is solid and responsive. To each his or her own with regards to keyboards, but there are worse out there.

This machine has a Nvidia 640M with a dedicated 1gb of memory. SO far, the laptop has been able to play all of the games that I have thown at it. While it is not considered a "gaming laptop" I am able to play Prototype II and Just Cause II on it with no lag. I usually try for the highest frame rate that looks good. This laptop has had no problems with medium/ high to hig res settings. I don't go all nuts with frame rate counters, I just know if it looks good when played. Is it smooth with little distortion? Yes. Is it jaggy or lags? So far, the answer has been no. It has really met my expectations.

The only drawback to this laptop so far has been the screen resolution itself. It is not as high as some similar laptop models, however, there is a big difference in price for those machines. After having used this laptop for a few weeks, I beleive it is a small compromise that I can live with.
The price war right, the size is right, the battery is right, the ability to play games and not have to haul around a 9-10 lb laptop is awesome!

I read the reviews and decided to get this laptop. Unfortunately most of the reviewers didn't own it long enough to provide the accurate reviews. I have used this laptop for 6 months and suffered by the automatically shutdown. When I lifted of moved the laptop, the the power just shut off. I sent it back for repair and they just upgraded the bios and the problem still persists. Now I have to use this laptop as a desktop or I have to carry it like a bomb so that system will stay alive when moving. I have owned many laptops and none of them has this "feature".

I use this Laptop since 3 weeks and its the best laptop/Ultrabook ever.
Its for 15" really small and the performance is very good.
For me as a student is it the best compromise between high performance(also for gaming), big screen and portability.
The battery is with up to 6 hours very good and it brings you through a whole day without energy.

I personally loved this laptop. It was beyond fast for simple and complex desktop functions. I could run multiple Adobe suite products without any noticeable decrease in performance. The machine boots quickly, faster than anything I've seen before. I really looked into a lot of different ultrabooks before finally choosing this one due to the combination of hardware specs which made this an exceptional value. I don't regret the decision.

Simply put, this laptop was everything I wanted in a device, to a point. I understand this isn't designed as a gaming machine, though I'd had some hopes that it would at least run many of the graphically-unintensive games. The issue I found was that the brick on the AC adaptor quickly overheated to the point it no longer provided a charge to the laptop until I closed the game and let the machine cool down a little. It was beyond disappointing. But again, this isn't a gaming machine, nor was I under the belief it would be. I had my hopes for a different outcome though.

When it came to running intensive software applications like InDesign, Photoshop, Premier, and other editing software, this ultrabook exceeded my every expectation. I multitask a lot and the machine could keep up with me every step of the way. The design really spoke to me and sold me to the emotions involved in owning a sleek and advanced ultrabook.

With regards to the game performance issues, the sellers were incredibly understanding and willing to work with me on this issue. While I ultimately returned the product in the end, this has been by far my favorite laptop yet. The speed of the machine, the layout of the keyboard, the lightweight nature, all of it was beyond fantastic.
