You are correct...it is ungrammatical for people to use the object pronoun by saying "as good as me." However, there are many, many instances in which spoken English is used ungrammatically in everday speech. Such grammatical errors are often regarded as being acceptable -- even appropriate -- in everyday speech. In such instances, to insist on grammatical correctness could even be regarded as pretentiousness.

Deepoe: I am a native English speaker who is studying grammatical correctness for the first time in my life in order to prepare for the GMAT. I am now amazed at how many grammatical nuances I was never aware of. I'm stunned.

The sentence correction questions in the GMAT are designed to exploit the testee's tendency to presume that English -- as it is spoken in casual interpersonal situations -- is grammatical, when in fact it is not.

I have a lot of hard work ahead of me. Right now I'm working my way through Manhattan GMAT's sentence correction book.

(I'm sure this message is loaded with grammatical problems as defined by the GMAT!)
