RE:  POST-EFFECTIVE AMENDMENT NO. 1 TO REGISTRATION STATEMENT ON FORM S-8

Ladies and Gentlemen:

         We have examined the Post-Effective Amendment No. 1 to Registration
Statement on Form S-8 to be filed by you with the Securities and Exchange
Commission on or about September 13, 2002 (the "REGISTRATION STATEMENT") in
connection with the registration under the Securities Act of 1933, as amended,
of 602,109 shares of your Common Stock, $0.001 par value per share (the
"SHARES"), consisting of 583,120 Shares to be issuable pursuant to the 1998
Stock Plan and 18,989 Shares to be issuable pursuant to the Extended Systems
Incorporated 2001 Approved Share Option Scheme (together with the 1998 Stock
Plan, the "PLANS"). As your legal counsel, we have examined the proceedings
taken in connection with the reservation of the Shares to be issued under the
Plans.

         It is our opinion that the Shares, when issued and sold in the manner
referred to in the Plans and pursuant to the agreements that accompany the
Plans, will be legally and validly issued, fully paid and nonassessable.

         We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to the use of our name wherever appearing in the
Registration Statement, including any Prospectus constituting a part thereof,
and any amendments thereto.

                                            Very truly yours,

                                            WILSON SONSINI GOODRICH & ROSATI
