The only things I would need would be:
-Browser that works with Gmail, Google docs.
OWB can do that.
-PDF reader (for resturant menu's
)
APDF is included with the OS and even if it's not fully compatible with everything, I've found it good enough to show that kind of things. Most ads, restaurant menus etc have worked here with it.
- Movie player like VLC
MorphOS version of mplayer is more than enough for that. I'd say it's the best version of mplayer on any platform

It has good GUI and works like charm. There's also VLC port available, but it's more immature and there's no need for it because of the excellent mplayer port.
-Bit Torrent clinet w/GUI
There are some clients, but they aren't as good as µTorrent etc on other platforms. You can get job done if you want, but I'd recommend to have some other spare machine for heavy use.
-Simple image editor
Included ShowGirls is just marvellous for digital photo handling etc. It does all the needed basic effects etc. But if you need more like drawing app, then there are many 68k options. ArtEffect, FXPaint, Photogenics, ImageFX, TVPaint, PPaint.. oh and included Sketch for simple drawing. Depends what you want to do in practise...
