To be fair, there are two types of complaints:
1. the system dependent complaints, about overall stability, performance etc. More often than not you can't really blame Steinberg alone for these (though other software often is more fault tolerant), and you certainly should not generalize going by a single system.
2. if a certain malfunction / bug can be reproduced identically on several systems, the ball is in Steinberg's field - unfortunately there is a boatload of stuff right now in 7.5 - what can you expect, they released an unfinished alpha version of 7.0 back then to meet the ominous X-Mas deadline, that's not how you write a good program. And much worse, they hardly did any serious bugfixing, and the few things they claimed to have fixed tragically were less than successful (7.06 "The windows configuration and layout of MixConsole is now fully captured and restored when using Workspaces" - rotflmao, brave claim !

Who wrote this obviously never ever used the program).
And finally, about people claiming not to have any problems - again, two types :
1. those that don't have any problems in general, ever - let them enjoy the honeymoon phase, when they finally start getting serious they'll see the (lack of) light.
2. if however somebody (who appears to be trustworthy) can't reproduce a certain issue you experience (and have provided a clear repro painting-by-numbers for), you should seriously consider having a system specific issue.
Unfortunately most long-standing complaints about 7.x are real Steinberg bugs, no two ways about it. The current crew doesn't seem to be capable of cleaning up the mess, or they don't care. Both is unacceptable ...
ymmv,

this is not directed at you, Bobby, can't check your issue since I uninstalled 7.07 and was wise enough not to upgrade to 7.5, all the 7.0 bugs seem to have survived the .5 transition unharmed.

I'm sure one of the happy 7.5 fans can spare 5 mins to doublecheck your issue.
