I have access to a few sealed first-gen iPads. Initially, I thought I'd just sell them via eBay as they continue to fetch a premium. Recently, however, I've wondered if there is an value in keeping one or two for a potential collector's market. Is there any history of Apple first-generation items increasing in value over the years? The volume in which these were produced and sold suggests that there might not be any significant market for them (at least beyond thier original asking price).
