Magnetism is a very weak force. Magnetic field strength dissipates in proportion to the inverse cube of the distance. It would take a magnet of roughly 20,000 to 30,000 gauss to erase a hard drive (with several passes of varying field strength) at extremely close proximity. By comparison, the average refrigerator magnet is 10 gauss as measured at the surface of the magnet. At a distance of 1/8" the gauss rating has dropped to 2, and at further distances, the field strength is diminished almost completely for measurable effects. For most magnets under 1/4 cubic inch (ferro-ceramic or neodymium) the field strength at more than 1/2" would be insufficient to damage any modern SATA HDD (which often use neodymium magnets with a gauss field strength of upwards of 20,000 for controlling the internal mechanisms, in addition to electromagnetic fields).
Sticking a fridge magnet on your computer case isn't going to hurt anything. You could even rub a fridge magnet on the outer surface of a 3.5" HDD with no adverse results. The enclosure is aluminum to prevent magnetic field induction, and the internal platters are purposely at least 1/8" to 1/4" from the outermost surface to allow for dissipation of all but the most intense magnetic fields.
Finally, you could rub a flash memory card directly on a 30,000 gauss magnet, and it won't have any effect, because flash memory is not magnetic storage. #cardreadermagnet
Magnets are not a problem. It's alternating magnetic fields that can mess up tapes, and the like. Memory cards are not affected by ordinary magnets. Try it at home. Put a magnet right on top of your SD card, move it around, leave it there for 3 days. Nothing will happen. #cardreadermagnet
Be as it may that a PC case probably provides enough protection against most normal magnets I still wouldn't feel comfortable with this nearby. Magnets screw up too many things to have them anywhere but a fridge. #cardreadermagnet
@Odin: Like what exactly? Unless you're still using floppies, modern media is all but impervious to magnets except those much stronger than you'd have available to you. #cardreadermagnet

Oh yes I'm well aware that stuff isn't that vulnerable and fragile. Still I'd prefer to keep my data away from anything even remotely harmful.
@sneakypoo: Brace yourself. Apparently there are hordes of idiots storming the gates who have no clue that flash memory cards are not magnetic media. Witnessing such ignorance, especially here, makes me wince, like having salt rubbed into a wound. #cardreadermagnet
@matt buchanan: I'm with you. I was nodding my head, thinking, "Yes, yes... this could be good." Then the unforgivable dearth of CF support made me look away. I abhor a multiformat card reader that forsakes CF under the guise of svelte formfactor. #cardreadermagnet
I understand that this doesn't literally apply, so bear with my word choice, but why isn't one female? (Like a plug) If I got them, I would want to keep them together to prevent tangling of the wires, thus connecting the lego blocks.
That's why I like my Zune headphones.
@Dacker:
Yeah, but since the general brick patent expired, their main claim against clones is trademark infringement on the basis that the 2x4 brick has been used on and off in LEGO logos for the entire history of their plastics division. The 2x3 brick enjoys no such trademark association, and therefore that simple distinction may be all that's needed to defuse any lawsuits before they happen. If they don't have an active patent, and they haven't ever even attempted to trademark that brick shape, it's a big difficult to come up with grounds for a lawsuit.
@Dacker:
Well, you have to realize that when they leased the original Automatic Binding Brick design from some guy in the UK, the _only_ part design was a 2x4 brick. It wasn't quite what we envision today, since the inside was completely hollow, and it was made from cellulose acetate instead of ABS plastic, but the outer shape is pretty much unchanged to this day. Well, the logos on the studs have been updated once or twice, and there was that period of time where some bricks had slots in the sides and/or ends (I actually have one of those), but any original Automatic Binding Brick should be able to connect to any modern LEGO brick and vice versa.
@Kaiser-Machead: Lego doesn't have a trademark on their brick design anymore anyways, so, there would be no reason for the company to not make it interlockable. Although, i cant imagine what you could do with them by adding more bricks....
@Marc Mohon: I dunno. The spacing of the dimples seems off, that or the dimples themselves are smaller than the standard. I wouldn't suggest adding other big bricks, but 1x1 pieces, like tile bits, would make for nice custom color schemes.
@Kaiser-Machead:
You mean the studs? They do look a bit undersized. The gap between them should be about 2/3 the width of each stud, where in this image it appears to be closer to a 1:1 ratio.
@paulrules: I'm guessing it's because the laser is directly under the thumb. Inthat sense, you are more likely to be able to relate to the absolyte positioning in the same way you do with a pen tip when writing.
Not having tried it, however, it's hard to say if it would make much difference. When I need a pen, I use my tablet and stylus.
@Shamoononon is tired: That's not much for a decent mouse, but I just don't know if that thing's any good. The Wacom tablet I got set me back nearly $500, so I figure $75 for a well built mouse isn't too bad. The ones under $30 are always junky for my needs.
@Shamoononon is tired: Yah, I do lots with Photoshop and some other nice programs. It's pretty important for me to get accurate and the stylus helps, and when I do use the mouse I want it to have some weight and be highly accurate.
However, even when just browsing around, a well-shaped mouse with a nice responsive wheel and good drivers (ie acceleration control, wheel adjustment, etc) can make even a mundane experience a little nicer.
As for trackpads, I absolutely hated them until I bought my Toshiba laptop. It's the only one I've used that is responsive, pressure sensitive, and has programmable gesture macros built into it. Still, I hook up a real mouse every chance I get, or my portable mini wacom.

And do you feel good about sticking a magnet on your computer? I don't... I'm not a gamblin' man.

I use mine to switch in between xterms for the most part and sometimes gaming although I'm fine just using the touch pad.
I haven't paid more than $25 for a mouse, EVER.
