I've been running two 64GB SSD's in RAID0 for about a year and a half, never had any issues and no performance degradation. I did synthetic and real-world benchmarks on the seperate drives and it's just way faster in RAID0. Nothing wrong with it (aside the fact that you seriously increase your failure rate, but that's not a problem for my personal laptop).
The fact that TRIM doesn't work isn't that big a deal at all. As long as your drive has decent garbage collection the advantages of TRIM aren't that high - not even remotely close to the performance gain from RAID0.
(Why did I start running in RAID0? It's the default config of my laptop. The Sony Vaio Z series always has either a 2x64GB, a 2x128GB, 4x64GB or 4x128GB RAID0 setup. Those 4x-RAID0's are blazing fast!)
