I'm happy with my stock 16GB running XP, but I should admit that I don't do anything on my Mini that requires a lot of processing power. I just use it for Internet/email, word processing (via Office 2007 Home & Student edition), etc. I upgraded the RAM to 2GB, turned off the page file, and decompressed the SSD
as soon as I received it, and now it performs very well. The only reason I would consider upgrading the SSD
is if I needed extra storage space for some reason. Otherwise, I don't know how I could justify the expenditure!
I'm sure others will have differing opinions, but that's my two cents!
