It's more of a clarification, not a drastic change. For example, the $27.63 is already in current law! Things like "similarly skilled worker" are just spelled out with more examples.
Current law (as of Jan. 7, 2011), from http://www.law.cornell.edu/uscode/html/uscode29/usc_sec_29_00000213----000-.html
(17) any employee who is a computer systems analyst, computer programmer, software engineer, or other similarly skilled worker, whose primary duty is—
(A) the application of systems analysis techniques and procedures, including consulting with users, to determine hardware, software, or system functional specifications;
(B) the design, development, documentation, analysis, creation, testing, or modification of computer systems or programs, including prototypes, based on and related to user or system design specifications;
(C) the design, documentation, testing, creation, or modification of computer programs related to machine operating systems; or
(D) a combination of duties described in subparagraphs (A), (B), and (C) the performance of which requires the same level of skills, and
who, in the case of an employee who is compensated on an hourly basis, is compensated at a rate of not less than $27.63 an hour.
That really isn't very different from the Proposed bill, from story:
(17) any employee working in a computer or information technology occupation (including, but not limited to, work related to computers, information systems, components, networks, software, hardware, databases, security, internet, intranet, or websites) as an analyst, programmer, engineer, designer, developer, administrator, or other similarly skilled worker, whose primary duty is--
(A) the application of systems, network or database analysis techniques and procedures, including consulting with users, to determine or modify hardware, software, network, database, or system functional specifications;
(B) the design, development, documentation, analysis, creation, testing, securing, configuration, integration, debugging, modification of computer or information technology, or enabling continuity of systems and applications;
(C) directing the work of individuals performing duties described in subparagraph (A) or (B), including training such individuals or leading teams performing such duties; or
(D) a combination of duties described in subparagraphs (A), (B), and (C), the performance of which requires the same level of skill;
who is compensated at an hourly rate of not less than $27.63 an hour or who is paid on a salary basis at a salary level as set forth by the Department of Labor in part 541 of title 29, Code of Federal Regulations. An employee described in this paragraph shall be considered an employee in a professional capacity pursuant to paragraph (1).
