Bear in mind that if you convert your drive to Fat32 and don't maintain a NTFS partition, if you do a lot of DVD ripping and frequently create a FULL DVD ISO image of 4gb, you can't store it on a fat32 partition...it is too large.
Also when I first started looking to instal Linspire. I DL it under a windows OS. I tried dl via the FTP (much faster then bitorrent-took me 3 hours to get 5.0 dl via linspire Gftp) and http links and the checksum never matched and wouldn't properly install... the internet connectivity would never work. However, I installed a oooold version of linspire and dl it (4.5)via the linspire os and the checksum immediately matched and I installed 4.5 fine.
I hope the support has improved also, it took them 3 WEEKS to answer my email about my installation issues. The response was try dl it again. If we don't hear from you within I think it was 48-72 hours we will assume the problem is resolved and close your case.
Yes, you have to be a CNR member to get 5.0 for free. (I am a CNR member) Klik-It is an alternative to CNR, but, if you aren't a CNR member it limits your support for the OS. Klik-It is an awesome awesome program with a programmer that put in countless hours to give an alternative to CNR. From all the post I read on the Linspire forum, all the time, EVERYONE loves it... and its free.
I have been running 4.5 for about 4-5 months, no problems at all since the initial install issue. And I have been able to find and use all the programs I need to use it for normal and general use an average user would ever need. I believe that if you want to try and run MS products on it, you can try a program called WINE (I think). I still use Windows to play my games though, and to do my DVD ripping and burning.
Just my couple pennies worth of experience with Linspire.
