Probably going to get another GB of memory for the Dell. It's struggling as a database development box with only 512MB of memory right now. Unfortunately, it's already got two 256MB DIMMS, so if I just got another 512MB of memory, it would then only have 768MB, which probably isn't worth the cost -- might as well go to 1.25GB total (since it only costs about twice as much to add 150% as it does to add 50%). Anybody need a 256MB DIMM for their Dell laptop? No? Yeah, I suppose you'd have to have a pretty pathetic configuration for that to do much good.
Okay, maybe "probably" was a poor choice of words -- I just finished ordering them.
Along those lines, thinking of upgrading the PowerBook to 1GB as well. Especially if I get Lightwave -- maybe next month.
