For now. They might change that eventually but up front I have a feeling they want everyone who bought into Gen1 to run out and buy a Gen2 drive to stay up with the latest & greatest. Makes sense initially from a purely business sense but long term it doesn't really work to bite the hand that feeds.
2. Gen2 is 2-2.5x faster in 4K random write IOPS than Gen1 (see anandtech)
3. Gen1 due to lack of TRIM can slow down at least 60% (in IOPS / write) after being in use (rec PC Perspective's test on this) compared to a fresh drive
4. Combining the above, in real-life use, Gen 2 can be 5x - 6x as fast as G1 in random write IOPS 4K
Well, they have already released software that can "restore" a drive to the "fresh" state. TRIM simply works to maintain that state - preventing the gradual degradation in performance that occurs without it.
And regarding speeds - I get the feeling we're going to see diminished returns on desktops. Let's say you have a jet that can go 1,000 mph and a second one that can go 5,000 mph. You're not going to see much difference between them if you take 30 mile trips (the equivalent of surfing, watching movies, etc). Now, if you have to fly 3,000 miles you will see a dramatic difference (heavy server loads).
