At Sony's Gamer Day conference, Sony released some pictures of their menu and online store and as you can see the PlayStation 3's browser looks a lot different that the PS2; it's in fact pretty similar to that of Sony's handheld, the PSP.

As far as the online store goes, Sony is offering quite a bit of stuff on day one in the form of demos and downloadable games and here's what you can expect in terms of demos:
- Blast Factor
- flow
- Lemmings 2
- Kazuo, Puzzle
- Mainichi Issho
- Ridge Race 7
The PSOne games that'll also be available on launch day (for Japan) will be:
- Resident Evil Director's Cut
- Konami Antics MSX Collection Vol. 1
- Konami Antics MSX Vol. 2
- Bishi Bashi Special
- Arc the Lad
- Jumping Flash!
- Everybody's Golf 2
- Silent Bomber
- Tekken 2
- Mr. Driller

At this moment in time there isn't any firmware that'll allow you to play those PSOne games on your PS3 so you'll have to make your peace by playing them on your PSP.
