I have two.
I got an Acer in Dec 08 as Christmas gift from DH. I got used to it being small, and boy is it handy to take around and manage the BnB. But...13 months after I got it (Jan 10), the hard drive went bad and needed to be replaced. WHAT A HASSLE. Luckily, DH bought it through Costco, which includes concierge service as well as an extended warranty. First, I couldn't get to ANYone live at Acer on the phone. Next, the concierge service managed to get through to them -- and Acer REFUSED to honor the extended warranty until I faxed them the receipt...even though Costco's service was the one who contacted them and the Costco rep was stating we bought the machine from them. So I faxed the reciept to Acer...and STILL couldn't get anyone to give me the time of day. All I could get was an automated voice telling me that, according to the serial number of my machine, it was not in warranty (and no option to get a live human). Back to Costco's concierge service, who gets a live person at Acer who says, "Oh, yes, we got your fax, but someone entered it into the database incorrectly."
So, NOW they agree to honor the warranty, but I have to send it away to a repair center. (In the meantime, I am freaking about how I'm going to keep tabs on reservations and the phone when I'm out of town). Eventually, Acer DID replace the hard drive and return my machine to me (where, of course, I had to reload all my software, which is a big time suck). It's a shame because I really like(d) the Acer. Bottom line for me here: Acer machine: like. Costco concierge service: like VERY much. Acer customer service: worse than non-existent.
While Acer had custody of my machine, DH found an eMachine netbook stuck in a corner in Wal-Mart. It cost us $225 (including tax) and so far is a little workhorse. the screen resolution is excellent (I'm not a techie, I just know it looks better) and the track pad has much better response. On one hand, it felt silly to get another, but for $225 it was worth the peace of mind to be able to monitor what I need to and have a back up. Hopefully, it will still work after 13 months.
