It seems that memory is much cheaper than before. This little unit (Acer AspireOne) has 1GB of memory and is perhaps the most powerful computer that I have ever bought on the basis of memory!
Even my desktop is less powerful on that respect and that’s after a memory upgrade. It’s really a good idea to bump up the memory. But I’ll be doing that at the purchase point in future. There’s little excuse these days for less than 1GB especially if you are using a resource hog like Vista.
