Since there are no moving parts, there is no difference in latency for
reading different sectors. This is the reason you simply don't care about
fragmentation. Regarding limitations on lifespan, there are many systems using
SSD for databases indexes, where the index is updated hundredth times a day and
the drive is specified to work for several years.
from personal experience, the build process is limited by I/O capabilities,
and this is where the SSD is just way beyond any mechanical disk. Real life
performance information give about 100 IOPS for Fiber channel / SAS disks, and
80 IOPS for SATA disks. for SSD the numbers go up to 5,000 IOPS - about 50
times increase.
Why upgrade if everything is working?
Windows XP is a a good enough operating system for most users, and unless you are running the newest games, any computer from the last 3 years is good enough.
There is still a reason to change, but for other reasons:
- change mobility -> laptop
- broken system due to viruses -> cheaper to get a new computer
- broken hw -> same as above
increased capacity / memory can be bought very cheaply now.

This just proves that being a monopoly allows you to ignore your users.
Excel is a major tool in many corporates, and having such an exploit can make havoc.
no the least, this shows that making your own rules can help you claim whatever you want - time to fix / number of vulnerabilities, etc.

- what are the most busy bands in term of actual usage.
- what is the strength of the interfering AP's.
- what is the actual SNR for your computer in the locations you work normally.
having this information you can use some of the methods above:
- directional antenna
- selecting the correct frequency
- setting the power
changing to a band can be an interesting idea but its more expensive than the others.

Open source is better because you can also state your objection to decisions and in extreme cases branch out. see my post http://design-to-last.com/index.php/Computing/open-source-makes-better-programs.html
