I have SSDs in my home PC (windows), work PC (Linux) and work laptop (Mac). In short - they rock!
I haven't heard of many problems in the large 1.5 generations of SSDs to hit the market. My old OCZ Vertex 2 died in my home PC after only 3 months, but they were known to be a bit dodgy and I was (sort of) a fool to be an early adopter. It was replaced with a newer and faster SSD without charge by Techbuy (who I'd bought all my PC kit from).
For doing your imaging processing on they are magic. My PCs are lightning fast. For a laptop the effect is even greater if you hibernate your computer - super fast saves from memory.
Personally I think the "sweet spot" is a 250 GB disk for around the $220 mark, though you can probably do better. The Samsung 840 series is very popular and successful at the moment

Hope this helps,
