My concern about JavaScript in the browser as the "VM of the Browser" is its lack of binary data support.

I think the poor support for primitive data types is one valid objection. Another, expressed eloquently by Steven Pemberton in his talk at XML Holland this morning, is that a language with weak data typing is increasingly hard to debug as the size of the program increases: the larger the program becomes, the greater the distance between the point at which a program is wrong and the point at which the symptoms appear; so development effort is much worse than linear with the size of the program.
