Right now, I am using my Sony VAIO TX650 laptop to type this response out; of which I purchased on Feb 2005 and I can tell you right now that I have had nothing but pure enjoyment on it! ^
This laptop like all of the current models in the Sony VAIO TX line have always featured solid state hard drives. In my case, I have a 50.1Gb Solid State HD manufactured by Toshiba and it has never ever given me any problems. The startup is great and the few times that I had to defrag the drive was very painless as the process takes a significantly faster amount of time over traditional hard drives with disk platters and heads.
There are other features that I could tell you about my laptop such as a 11" diag XBRITE LCD screen with a screen depth from outer lid to surface of less than 2mm thick to weighing in at just under 1.8lbs (.76kg), but the point is: if you are willing to make the extra investment in hard drive technology, then go for it.
I paid about $2800 for my laptop and ever since then I have never ever regretted this purchase since. Quite simply put: you get what you paid for.
