All of these have done well for me in the past. I will try to sort them out by type, and give a quick blurb about what they offer.

Services:
Crashplan
http://www.crashplan.com/
Offers a wonderful backup program that allows for online and local backups. The online service is paid, but worth it.

Amazon Web Services
http://aws.amazon.com
Both their EC2 (virtual servers) and S3(storage) services are great performing, very flexible, and can be very inexpensive.

Google Apps
http://www.google.com/apps/intl/en/group/index.html
Lets you have a host of Google services for your own domain for free up to 10 users. Easiest way to get email for your company, and has some of the best features on the market.

Prey
http://preyproject.com/
Lets you track and recover stolen or lost laptops, desktops, and android phones for free. Can also lock and turn on an audible alarm on a lost phone.

Vipre Antivirus
http://www.vipreantivirus.com/
If you aren't confident enough in Microsoft Security Essentials, this is the antivirus for you. I've never had it fail, and it's incredibly lightweight.

Feral Hosting
http://www.feralhosting.com/pricing
Provide seedboxes (torrent hosting), great speeds, awesome selection of software, extensive FAQ, best cheap bandwidth you will be able to find.

Thrust VPS
http://www.thrustvps.com/
High performing Virtual Private Servers with an emphasis on transparency and customer service.

Merchants
Newegg.com
http://www.newegg.com
Sell electronics, but offers the biggest selection, the best searching, and honest user reviews. Excellent customer service as well.

Projects
Transmission
http://www.transmissionbt.com/
Bittorrent client. Free, fast, simple and Open Source.

Linux Mint
http://www.linuxmint.com
Customized version of Debian or Ubuntu with an emphasis on working out of the box. Includes lots of programs, and has the most used plugins already installed and configured.

Drupal
http://www.drupal.org
Flexible, free and fast CMS. Powers this website, but can be more difficult to operate than some alternatives.

Wordpress
http://wordpress.org/
Easiest blogging tool available. Can be used to power a whole site, but not as flexible as Drupal.

DD-WRT
http://www.dd-wrt.com/site/index
Supercharge your router with DD-WRT firmware, lets you do all sorts of fancy things with it, and improve the performance to boot. I only buy routers that are DD-WRT capable now.

Chromium
http://www.chromium.org/Home
Open source father of Google's Chrome. Fast, includes all plugins, great bookmark sync, and updates silently and invisibly.

Debian
http://www.debian.org/
Free, fast, and stable linux OS. I use Debian on both my desktop and on my web server, and it's equally suited for both. My favorite distribution.

Products
Buffalo
http://www.buffalotech.com/
Buffalo offers a whole series of wireless routers that run DD-WRT from the factory, and they are awesome. Fairly cheap, and come with two year warranties. I run two at my house.
