What else ?...

Today (thanks to lifehacker web site) I discovered a curious list :

61 Free Apps We're Most Thankful For

I have to admit I already used most of the top ten ones, for private or professional use... Most of daily use of IT tasks are covered here. So for a company, specially on these hard times, the question is : what else ? Why to pay more !

I suggest here some questions IT Manager should ask before switching to free app :

Is there any return on investment ? 

are thezy reliable ? 

what about security ?

what about the long term developpments ?  

is there a support available ?
does this soft needs long term training ?

We were used to ask these when buying software. We should not forget them wimply because it's free.

Last but not least, never forget to test a free app (on key platform with key users)before company launch !

 Question : are you using professionaly one of these ? why and how ?

PS : I trend to work more and more on web application or services , but this is another question
