Debian-based Linux distributions, which use the .deb package format and the apt package management system, are relatively free from dependency hell and thus are generally a joy to use and maintain. However, in order to properly manage a local archive of packages you need to build a repository in which to keep them. This is the simplest recipe I know for putting together a HTTP repository.
Ubuntu is a high-quality Linux distribution based on Debian Linux. It provides various distributions customized to various purposes; Ubuntu, the "default" system, is based on GNOME. There are also Kubuntu (KDE), Xubuntu (XFCE), Edubuntu (educational, and provides LTSP) and possibly other official distributions; depending on whether this page is outdated, a DFSG1-style distribution in which all source media must be Open-licensed, as in GPL, BSD, Creative Commons, and/or Public Domain only. In addition, Ubuntu provides absolutely the highest level of driver support (at the expense of Free Software "purity") including nVidia, ATI, Intel, and other manufacturer's binary drivers.
I wanted to play Neverwinter Nights on Linux, and didn't have it installed anywhere. Today, the easiest way to install NWN for linux (by far) is to use the current installer from Bioware; you can even download the game content from them, although you will need your own registration code. The code from the Windows version works fine. However, I'm on a modem and downloading that much data is out of the question. It could take me days to download the patch, alone (I get 26.4kbps on average - life in the country is swell.)
While Linux marches ever closer to being user-friendly, there are still a few loose ends to be tied up. Networking continues to be a bit of a sticky spot, and Bluetooth support is definitely in need of some refinement. But another area, and one which you would expect to have been tied up nearly by now, is sound. The PulseAudio server can help you take care of this problem, but simply installing it doesn't clear up the problems with programs taking the sound card and never letting you have it back.
Sun co-founder John Gage, who coined the phrase "The Network is the Computer" which later became a Sun slogan, is today entirely correct. Oh sure, he's not semantically correct, but he's basically correct in that the true power of the computer is not realized until it is connected to something. MP3 players are little computers that are networked to your computer long enough to load music on to them, for example. One useful and basic thing we can do to cause computers to participate with one another is to copy files between them. Sometimes it's most effective to just do this with a disk, but if they are connected to a network, it's usually easiest to copy the files that way, if not fastest.
The HP iPAQ H2215 is a 400MHz Xscale-powered Windows Mobile PDA. It ships with Windows Mobile 2003 (Windows CE) and has an SDIO slot, a CompactFlash Type II slot, and bluetooth wireless functionality. The unit has a rotated 3.5" QVGA screen (240x320) which displays 16 bit color, and is powered by a 900 mAH Lithium-lon battery (or an optional 3600mAH battery which makes the unit quite a big larger.) All in all, this is a credible PDA, but I do wish it had WiFi.
