In this day and age, I would think quite a few times about anything=20
which dissipates any amount of heat, since heat is generally a=20
indication that the design isn't very green, which isn't very popular=20
nowadays.

Unless you have a good reason for it, and can explain it in a way that=20
makes sense, I would avoid anything which gets much above ambient.   And=20
by 'explain', things like my motorola droid which gets hot when charging=20
plus navigating plus setting in the sun on my dash makes sense.   Or say=20
if you were doing something very computing intensive and it gets hot=20
when you do that - I.E. heat from heavy work is acceptable, heat when=20
idle or under simple tasks is not.
