Yes, there seem some misunderstanding. Normal users don't need anything. SSD works just as is, and it's fast enough.
If you are adventurous, you can go quest for the performance optimization with TRIM support. But normal people don't need it at this moment. So, arguing about the usability for normal users doesn't make sense for now.
Thanks for the reassurance. Everybody on the internet seems to be talking about TRIM etc when it comes to SSD, that's why it looks to be so important (even the openSUSE wiki focuses on TRIM). Without having the proper technical background in ATA, filesystem, and SSD technology, it's difficult to know who's right and who's wrong. Anyway, the SSD works fine for me at the moment and indeed a lot faster than a normal HDD. We are currently running some tests to see whether we could use SSD technology for our large Linux clusters where we need fast scratch disks on each cluster node.

Thomas,
RE: http://en.opensuse.org/SDB:SSD_discard_%28trim%29_support
I've been working on the SSD discard page. In particular, I added an intro to the wiki ssd article to this effect:
=== This article discusses a specific SSD feature and what some may consider a shortcoming. This "shortcoming" in no way means that SSDs are not a good solution with openSUSE today. Basic SSD operation is supported in all released versions of openSUSE and provides full ATA-7 support and significant performance improvements over rotating disks are seen for most SSDs with most workloads. It is only the new ATA-8 TRIM feature that is not yet fully implemented nor optimized. Not having this single feature fully integrated into openSUSE (or the linux kernel in general) is no reason not to benefit from the significant performance gain available in modern SSDs. ===
Hopefully that makes the situation more clear.

Very good Greg, with this introduction, I can better understand, and now I'm back in trouble in which ssd to choose.
