Ladies and Gentlemen:

     We are acting as counsel to Dell Inc., a Delaware corporation (the “Company”), in connection with its registration statement on Form S-3 (No. 333-155041) (as amended, the “Registration Statement”) previously declared effective by the Securities and Exchange Commission (the “Commission”) relating to the public offering of debt securities of the Company that may be offered and sold by the Company from time to time as set forth in the prospectus dated March 14, 2011 (the “Prospectus”), and as may be set forth from time to time in one or more supplements to the Prospectus. This opinion letter is rendered in connection with the proposed public offering of up to $300,000,000 aggregate principal amount of the Company’s Floating Rate Notes due 2014 (the “Floating Rate Notes”), $400,000,000 aggregate principal amount of the Company’s 2.100% Notes due 2014 (the “2014 Notes”), $400,000,000 aggregate principal amount of the Company’s 3.100% Notes due 2016 (the “2016 Notes”) and $400,000,000 aggregate principal amount of the Company’s 4.625% Notes due 2021 (the “2021 Notes” and together with the Floating Rate Notes, the 2014 Notes and the 2016 Notes, the “Notes”), as described in a prospectus supplement dated March 28, 2011 (the “Prospectus Supplement”). The Notes will be issued pursuant to that certain Indenture, dated as of April 6, 2009, as supplemented by a Fourth Supplemental Indenture, dated March 31, 2011 (the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”). This opinion letter is furnished to you at your request to enable you to fulfill the requirements of Item 601(b)(5) of Regulation S-K, 17 C.F.R. § 229.601(b)(5), in connection with the Registration Statement.

     For purposes of this opinion letter, we have examined copies of such agreements, instruments and documents as we have deemed an appropriate basis on which to render the opinions hereinafter expressed. In our examination of the aforesaid documents, we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the accuracy

and completeness of all documents submitted to us, the authenticity of all original documents, and the conformity to authentic original documents of all documents submitted to us as copies (including telecopies). As to all matters of fact, we have relied on the representations and statements of fact made in the documents so reviewed, and have not independently established the facts so relied on. This opinion letter is given, and all statements herein are made, in the context of the foregoing.

     For purposes of this opinion letter, we have assumed that (i) the Trustee has all requisite power and authority under all applicable laws, regulations and governing documents to execute, deliver and perform its obligations under the Indenture and has complied with all legal requirements pertaining to its status as such status relates to its rights to enforce the Indenture against the Company, (ii) the Trustee has duly authorized, executed and delivered the Indenture, (iii) the Trustee is validly existing and in good standing in all necessary jurisdictions, (iv) the Indenture constitutes a valid and binding obligation of the Trustee, enforceable against the Trustee in accordance with its terms, (v) there has been no material mutual mistake of fact or misunderstanding or fraud, duress or undue influence, in connection with the negotiation, execution and delivery of the Indenture and the conduct of all parties to the Indenture has complied with any requirements of good faith, fair dealing and conscionability, and (vi) there are and have been no agreements or understandings among the parties, written or oral, and there is and has been no usage of trade or course of prior dealing among the parties that would, in either case, define, supplement or qualify the terms of the Indenture. We have also assumed the validity and constitutionality of each relevant statute, rule, regulation and agency action covered by this opinion letter.

     This opinion letter is based as to matters of law solely on the applicable provisions of the following, as currently in effect: (i) the Delaware General Corporation Law, as amended; and (ii) the laws of the State of New York (but not including any laws, statutes, ordinances, administrative decisions, rules or regulations of any political subdivision below the state level). We express no opinion herein as to any other laws, statutes, ordinances, rules, or regulations. As used herein, the term “Delaware General Corporation Law, as amended” includes the statutory provisions contained therein, all applicable provisions of the Delaware Constitution and reported judicial decisions interpreting these laws.

     Based upon, subject to and limited by the foregoing, we are of the opinion that the Notes have been duly authorized on behalf of the Company and that, following (i) receipt by the Company of valid consideration therefor and (ii) the due execution, authentication, issuance and delivery of the Notes pursuant to the terms of the Indenture, the Notes will constitute valid and binding obligations of the Company.

     In addition to the assumptions, qualifications, exceptions and limitations set forth elsewhere in this opinion letter, our opinions expressed above with respect to the valid and binding nature of obligations may be limited by bankruptcy, insolvency, reorganization, receivership, moratorium or other laws affecting creditors’ rights (including, without limitation, the effect of statutory and other law regarding fraudulent conveyances, fraudulent transfers and

preferential transfers) and by the exercise of judicial discretion and the application of principles of equity, good faith, fair dealing, reasonableness, conscionability and materiality (regardless of whether the applicable agreements are considered in a proceeding in equity or at law).

     This opinion letter has been prepared for use in connection with the filing by the Company with the Commission of a Current Report on Form 8-K relating to the issuance and sale of the Notes, which Current Report on Form 8-K will be incorporated by reference into the Registration Statement and Prospectus, as supplemented by the Prospectus Supplement.

In giving this consent, we do not thereby admit that we are an “expert” within the meaning of the Securities Act of 1933, as amended.

Very truly yours,
