Stupid limit on email size

As more and more documents become fater and fater, it find increasingly difficult to sent email attachments over 7 to 8 MB. This is becoming very annoying and I have to rely more and more on services such as yousendit.com. The funny thing is that most people think that this limit is normal. Is this 1999 or what ? Am i the only one to think this wall of 10 mb attachment is stupid ?

Let's do the math, increasing from 10MB to 20MB for a 200 people company will increase storage capacity by 2GB !! Cost for the company: $4. Let's assume this company uses raid 5 disks and keeps all email on the server for one month, the cost is still a mere $600...
