We claim the ornamental design for a computing device, as shown and described.
FIG. 1 is a front perspective view of a computing device;
FIG. 2 is an enlarged view of a section of the computing device of FIG. 1 taken along line 2 of FIG. 1;
FIG. 3 front view thereof;
FIG. 4 is a sectional view thereof taken along line 4-4 in FIG. 3;
FIG. 5 is a top view thereof;
FIG. 6 is a left side view thereof; and,
FIG. 7 is a right side view thereof.
The portions of the computing device shown in dash-dash broken lines in FIGS. 1, 3 and 5-7 are for environmental purposes, the short-dash long-dash lines in FIG. 2 are boundary lines, and the dash-dash vertical and horizontal broken lines shown cutting through the front, top and sides of the computing device in FIGS. 1, 3 and 5-7 indicate an indeterminate length, it being understood that none of the broken lines form a part of the claimed design.
