1) Default to 240: I want to be able to always watch videos in the worst resolution possible. I want the lightest bandwidth possible. I'd sometimes be happy with just the audio. It seems that I can't default to 240, no matter what I click.
2) Small elements in UI: There is a teeny little grey drop-down arrow at the top of the Subscriptions list. I didn't see that for weeks, and the randomly changing order of the subscriptions menu drove me bonkers. Making that arrow bigger would be good.
3) Default to Uploads only: When I click a name in the subscriptions list I want to see the videos they've uploaded. I probably don't care about other videos they've liked. And if I do I can clicky the menu. Making me clicky the menu for something I do every time is sub-optimal.
4) Please god something for comments: Google and YouTube are full of smart people. Some kind of "poor comment quality" filter should be easy to implement. Allow youtubers to have no comments; full comments; or 'no poor comments'. (Maybe with a 1, 2, or 3 level setting). This would stop people posting "FIRST!!" and then getting into flamebaiting over it. It could stop some of the vile juvenile language use. (Seriously, I can string all those words together, but I can't show a nipple?) It's not a cure for poor comments, but it could help.
I don't know what iGoogle is. Seriously, I think I'm signed into it. Or maybe I signed out when I found out it was going.
I'm not quite sure where you're going with the MS thing. For years they've had "sweet spot" OSs. MSDOS 3.3 was good; MSDOS 6 was good. Win 3.11 for workgroups was good while the other win 3.1s were bad. Windows 98SE with plus pack (is that right?) was good, while all the others were okay. Windows 2000 was god tier. Windows ME was a crime.
