Product review (5 stars): So quiet you wonder if it's washing!
We purchased this Bosch dishwasher SHX98M09UC after much Internet research 2 months ago and have used it every day since.

The dishwasher is light enough to be maneuvred into place by one person and the installation was rather simple with the very complete instructions provided. The operation manual is also clear and the controls easy to understand.

The design is stunning: all stainless in the front, with a heavy-duty handle and very nice digital display on the facade, although the actual touch controls are hidden on top of the door. The inside is stainless steel also, great at retaining heat. All accessories are high grades and we appreciate the adjustable top rack and removable silverware holders. As with all stainless appliances, it's hard to keep it looking clean very long as it shows finger prints a lot more than painted appliances.
The drain is covered with an easy-to-remove filter basket that we have not had to empty yet in 2 months of use (I understand some cheaper dishwashers have small "garbage-disposal" instead of a collecting basket, and those can fail or not always work properly as well as being noisy)

It's energy efficient as I understand the drying is performed by the heat retained in the walls of the washer. So far, we have not observed any difference in our electric bill.
I believe it also uses small amounts of water (it's a very small water line going to the washer and a few seconds are always enough to pump enough water for the program. Emptying is also very quick)

The cleanliness of the dishes is good on the Auto Wash program, which we have been using most.
With the recommended drying agent, glasses and fine china come out looking very good with no water spot.
Heavy soiled pots may need a little rinse before the wash, especially with some caked-on food, such as eggs.
Plastic ware comes out OK from the top rack and, with the limited heat of this dishwasher, is not warped.

The main reason why we decided on this washer is the noise rating: the quietest we could find in our price range. And on this point, we were just blown away! The first time we turned it on, we had trouble believing it was running! Our kitchen is open to the living room and now, no need to turn up the volume on the TV when the dishwasher is running (big difference from the old Whirlpool we had before). To me, this only is worth the high price tag!
Even the water emptying into the sink pipes is very quiet.

Before buying, I had considered the equivalent Kenmore Elite (same price) but the noise rating was 4 dB more (3 dB= double the noise!) and the racks a tad flimsier at first look. The Kenmore Elite had more gadgets such as a "turbo wash" nozzle, knife holder and additional washing programs and options. In general, I prefer simpler systems that are reliable and of high quality so I am very happy with this Bosch choice.

I would warmly recommend this appliance if you need a new dishwasher that doesn't rattle and wake you up!

UPDATE 2010: We have been using the dishwasher for nearly a year now and it's as great as the first day we got it.
The drain basket rarely needs emptying, the dishes are clean and never damaged (especially plastics), the washer is very easy to operate and most of all, it's so quiet it still surprises us!
Don't hesitate: this is an excellent buy!

UPDATE 1/27/2012: I am surprised to see that so many reviewers report issues so I wanted to add a couple comments:
Here, the dishwasher is going strong and it still looks as good as when we received it.

We have had one hiccup when we moved to Costco's Kirkland liquid dishwasher detergent: the dishes were no longer as clean as expected and it took us a while to figure out that going back to the tablets Bosch recommends for their machine would bring back the perfect performance. In the meantime, another liquid detergent gave us very poor results too (can't remember the brand?): it seems that this dishwasher should be used with tablets only.
Since going back to the recommended (is it Finish? It's the ones with the red ball in the center) tablets, we couldn't be happier!

I also noticed comments about dishes not being dry. I wanted to mention that we always use a rinse/dry agent (the washer indicates when it runs out). We have been changing brands depending on availability/sales so it must not be as important as using tablets. The only time the dishes are not completely dry is if you open the washer before the end of the program: it's a bit tricky because it sounds like nothing is happening anymore when it is drying; it is totally quiet but the display gives you a drying time.

I wish all could be as satisfied as we are...
