Personally I disagree about the SSD. Plainly the "sweet spot" on SSD pricing is the 120/128GB. The price increase is only $20-30, the $/GB is much cheaper, the speed will be higher, the longevity improved, and you simply don't have to worry about what you put on it. The prices have come down so far that it's more cost effective to buy a 120/128GB drive. I won't buy anything smaller these days.
I'm not replacing the 64s I have either, but at least since late last year I've only been buying larger ones. For my main HTPC I paid $140 for a 64gb Plextor M2 about 16 months ago. For a desktop build about 3 months ago I paid that same $140 for a 180GB Intel 330. When I bought the 64, a 128GB Plextor would have cost me over $300, which was simply excessive, but now really good 128s can be found almost every day for under $100 which makes them the right choice.
