yes, I own an ASUS X83v and as for tech support I have not found them any worse than say microsoft, at least in my experience their tech support has one MAJOR benefit: their reps are trained enough to speak proper and understandable American english, not indian/pakistani english (no racism intended, but for us americans its just a really annoying hassle that we have to make an effort to communicate using our own language!)
I'm a big time hater of DELL due to at least one very major flaw: their internal design is MESSED UP, they use the stupidest, most populist approaches to internal airflow such as a dedicated air tunnel for CPUs which results in clothe-dryer like clogging in todays dirty atmosphere, and if u r a smoker or live in beijing, u will need very regular cleaning. also the color and quality of their LCD panels and their wal-mart like pricing speaks to their overall component and built quality.
u see, all of these companies contract other firms usually in china to produce these components for them and then they just assemble them with a couple of parts of their own brands most likely and sell it to us. so it matters
ASUS notebooks have very solid built and high quality components. also the internal design is quite practical. see, i'm a smoker and i smoke frequently around my notebook, just 9 months into ownership i opened the bottom panels for an internal clean up and i didnt even have to to worry about take anything out, as from the fans i could tell the smokedust issue is not too bad and i'm assuming this is due to their airflow channels/filters because in 9 months i have seen many computers get a lot more dust!
Since i purchased it back in early 09, their respectfulness @ customer dpt has increased according to my personal experience. i rated them 2/5 the very first time i talked to them, and i didnt talk to them until then ear 1 year anniversary point when thnx to windows vista being just a windows and things getting messed up with one mysteriously failed .net framework 3.5 setup, i had to do a full recovery and needed to ask them a few clarification questions before i popped in the DVD.
their software is also quite reliable unlike manufacturers like hp who are notorious for buggy and problematic drivers/software for various lines of products including notebooks and printers.
their recovery disk is essentially a bootable windows vista that does allow a clean install with your own customized partitioning set prior to setup and separately unlike other recovery disks that are very limited in what they allow u to do with, some only restoring to original factory settings or forcing u to use your own licensed products to go for an old school OS assembly!
They are also priced rather well for the performance, not too cheap and not ridiculously expensive, so far i have had no problems with the performance, except for usual laptop shortcomings such as high temperatures and of course not the same gaming fps as an equal-spec's desktop machine. but still 4 gb of ram and 1 gb of dedicated ddr3 for nvidia 9600m GS is not a bad combination for the $1100 total (incl. tax) i paid at best buy, throw in their 18 month no interest financing too and u got a customer who has long ago seen some amazing ASUS cd burners which are sadly not around anymore. after all asus is not perfect at making everything, but they used to have really really reliable cd burners in the good old days of 90s and early 2000s
