I beta test products for Cooler Master on occasion and I've been participating in the Uncharted 3 beta which is ok. No beta browsers or software for me (except games/mods in rare circumstances).

I like to do beta stuffs sometimes if they are my favourite software but I am not definitely beta crazy.

I'm not in any betas at the moment, but I typically end up doing something most of the time. I also used to do quite a bit of alpha testing back in the day when PC gaming was kind of a niche market. I alpha tested Wolfenstein 3D when I was in high school (yeah, I just gave you a close estimation of my age, didn't I), as well as Quake, Rise of the Triad, Duke Nukem 3D (they didn't want me for the new one...) and the original Diablo.

However, most companies do alpha testing in-house now and don't use out-source downloaders (I actually had to dial up long distance to get my updates for Wolfenstein!) due to the risk of it hitting the net or worse, being sold! (Remember HL2 and the BS delays there?)

I also beta test Microsoft OS and Office products, though I didn't get Office 2010 (I hear the beta group was very small for it). Microsoft also seems to be moving away from external "official" beta, as well, as we saw the Windows 7 out for free download on the web. When I tested XP, I got a free copy. When I tested Office 2003, I got a free copy. Office 2007? Nope, and my beta erased itself when it released.

Added: I lied! Firefox 5 beta is allowing me to type to you! Oops, no, it looks like 5.0 is now a final release! I DON'T EVEN KNOW ANY MORE!

I'm a MASTA BETA!!

Mostly games and some software but I am very careful when it comes to operating systems like Windows. Usually I run them in a virtual machine via Windows 2008 on my 771-Xeon workstation. Although I do have a very unstable Debian system installed on my old PC but there's nothing important on it so a few crashes won't hurt me much.
Never drivers unless there are no others because of a product no longer being supported by newer operating systems and or the manufacturer.

Sorry but I can't tell in which beta and alpha software I am participating in at the moment (NDA restrictions).

I never download beta drivers because most of the times they're pretty unstable, but when it comes to games I will defenitly try the beta to see what it's like before the full release. I would defenitly NOT install a beta OS!

Definatly not, I dont get why people would

Not for gaming. I do beta testing when there are applications and operating systems that interest me, so when it comes out into beta, I will be beta testing it.

Yeah I'm sort of a beta freak, I'm always running an Alpha/Beta version of Chrome Browser, or Firefox, etc.., but when it comes to beta versions of an OS however, I tend to play it safe, and wait for the full thing.

Most of the beta stuff I do is the game ones. I tried a beta of one of the Firefox versions, got me P.O.'d waaay too much for my own good.

I've done some hardware beta testing for Cooler Master.

Yes I bought Windows Vista :D

I love to do beta testing, I tested a lot of things including games, programs, etc.

oh and that goes for canadians to,as you are really yanks also

i love beta stuff - but its bee-ta not baita as in fishermans bait,noo bait-a make sure u yanks get it correct. bee-ta,its called english and i am in england, thats why im right, unless you start talking obamaish.

I often try beta software. I worked a long time with windows 7 Beta and RC. Also browsers like firefox,... Never graphic card drivers because of the stability issue. A couple of games if they are really interesting.

I'll try almost any beta except drivers.

One word, Minecraft.

I like to beta test. Especially because you can give feedback to the developers to make the game or software even better. I once did Firefox and Windows 7.. I really only beta test games. Love it =D I have no patience D:<

I'm patient enough to wait for the full finished product. I'm too lazy to install, and then uninstall temp stuff.

Yeah, because they are mostly free.

only games

Like Boov i do Alpha testing too, but most Beta testing because i easery to get into :D
I have played Rift Beta and Alpha
Need For Speed World Beta
APB Beta
Just a few of the games i have played in Beta / Alpha

And ofc have I used Windows 7 Beta and RC from the start <3

-Cb

anyone who plays games is a beta tester. if it wasnt a beta it wouldnt need patches

Beta is too mainstream!
I do ALPHA!
