Narrow minded view.
But the following 6 months will mean that you now have a new alternative OS to play with without spam/advertisements with new bug/security fixes, likely more corporate unfriendly (filesharing/VOIP etc etc) features, removal of OS restrictions, and lack of branding. Finally when Dell decide to no longer support the device the community will still be there to do it.
Dell should have factored the GPL source release timetable in advance, or even better released it while they worked on it, so it's not the open source "nutters" fault if Dell cut corners (hypothetically - they probably can just release it).
Average Joe (c/o Anon Coward) needs to see the bigger picture of open source instead of narrow mindedness that only a few "nutters" need it - it'll benefit everyone and competition is always good. Where would we be today if Netscape Navigator wasn't open sourced (Firefox)? or Sun's Star Office (Open Office), Minix (Linux/Unix/Ubuntu etc), Berkeley sockets (networking layer in Windows) etc etc.
Rant over :)
