I don't use chat or p2p software, so I can't comment on that... ;-)
I also assume we're talking about stuff that comes with the OS. For stuff that doesn't, hey, what *shouldn't* you have availabe? :-D
1) Digital camera suite - The ability to download and organize photos into albums, full DPOF support for online ordering or printing, ratings by megapixel and quality settings (rather than pixel dimentions and technical JPEG metaformat gobblygook), and a proper, standardized naming system. Slideshow screensavers and books on CD are nice, too.
2) Image viewer - More like ACDSee, less like IE or MultiView.
3) Seperate CD, Video/DVD, and Audio players. I HATE all-in-one apps.
4) A tool to easily manage drivers, codecs, and other stuff people shouln't have to know about, but do, anyway. It should also say if a product is 1st party or 3rd party, so users know what came from the manufacturer and what didn't.
5) A very simple DRAG-AND-DROP file converter. I hate it when people send me screenshots in BMP format, and people bitch that they don't know how to convert PNGs into JPEGs, and so on. Batch and whole-folder processing is a must.
6) Word processor that saves in RTF format, or similar - I can't stand people who use Microsoft Word or some other high-end office suite to write a damn memo! You don't need a word processor to write a book report, but you do need a built-in dictionary.
7) An FTP client that works like a folder, and properly describes how CHMOD works - I despise all the CuteFTP clones with muti-windows, tree listings, ubiquious buttons galore...

Hardware information tool - A standardized way to monitor or update the BIOS, tell things like temperatures, fan speeds and internal problems, what accessories are in the computer, any special buttons you have on the front of your case (push a button and the machine schedules a backup, etc).
9) DECENT backup software - Something that doesn't just catalog your drive and duplicate files, but exports files onto any CD/Tape/HD/Filesystem/Network, and also ensures data integrity, instead of just making copies.
10) A very basic programming tool, like what AMOS used to be. Open windows and perform scripts by pushing buttons, open a screen and blit graphics around, graph charts, play music, write games and HAVE FUN with your computer! Decent mutimedia libraries for a GCC compiler would suffice in a pinch, but a very simple scripting language that combines the best parts of Java, Perl, and BASIC would be awesome. The ability to write your OWN software was always one of the best things about the C64, Amiga, and Atari, and it's a shame PCs and Macs haven't followed up on that homely computer tradition. The ability to easily make your own USB devices and drivers would rock, too, though that's a bit too narrow a market. ;-)
Spihunter: If you want to do Office stuff, accounting, or CD burning you might as well use a cheap x86 box with Linux/Windows to do that stuff. Walmart has a linux/x86 box with a 1.2 ghz Duron for $200.
Oh my God, that machine is such a piece of junk. :lol:
