[Asus Transformer TF700] permutations:
My observation is that it's hit or miss with Asus products. Sometimes they work great, and sometimes they break prematurely. When they break, you can have big problems. I've read MANY reports of people sending in the TF700T for warranty repair and not getting it back for months, and not getting replies from Customer Service. When the machines did come back, the problems usually weren't fixed. The BBB assessment was updated on January 14, 2013 and the complaints were the same - long delays in getting machines back, and when they came back, the problems remained. So it's not just the Prime.

I loved my TF700T when I first got it - awesome display, loved the dock, etc. But there is something wrong with the memory management. Android isn't supposed to run out like that. My phone doesn't (Motorola Droid X Maxx HD). And the constantly hanging and crashing browsers - reported all over the internet - drove me nuts because I mainly use it for browsing the internet. I tried more than 5 different browsers - all had the same problem. I read a thread in this forum where someone discovered it was related to the TF700T's unusually slow I/O performance. Browsers are heavy users of I/O and memory. The TF700T, besides its memory management bugs, has only 1GB of RAM. I wish it had 2GB.

When the battery meter stopped working (all battery meter apps - the TF700T was reporting its battery level incorrectly) and my first efforts at recalibration didn't work, I went to the Asus site to inquire about customer service and/or warranty support. Their Web site is broken in several places. You can't get a list of local authorized service centers, for example - try it. Plus the Web site is in broken English, and and the support parts are unprofessional and not very confidence-inspiring. I'd already heard some complaints about warranty service problems, so that made me nervous. That's when I started looking at the 1-star Amazon.com reviews and found the links to the BBB alert, extremely low customer service scores, tales of horror, etc.

Others have reported problems with broken pins in the connector to the dock (it's plastic and delicate), and cracks in the casing around the screen - lots of reports of these.

For me, the TF700T was not usable because of the memory management problems and browser stalls/crashes. For someone using it mainly for other things, these problems might not matter so much. The quality control and customer support/warranty problems were the last straw.

I know many people are happy with their Nexus 7's, which are made by Asus. I'm told Google warrants this, so the risk is lower. I'm looking at the Nexus 10, which is made by Samsung.

I'm not comfortable with Asus quality control. They cut corners in places, using some high-end components and some very cheap components. The slow I/O on the TF700T is a case-in-point. I'm even more uncomfortable with Asus customer service and warranty support. It's all very hit or miss. Some people are lucky and their machines hold up, and some are not. Some luck out with customer service and some don't. I don't want to do business with a company like this. If it doesn't bother you, then fine. I'm just posting the warning for those who don't like high-risk purchasing. To each his own.
