32 bit is another limitation. The above link gives a list of 10 distros that still support 32 bit and therefor are also lightweight. A lightweight browser would be best too. No running firefox with 30 open tabs. Falkon is a pretty good one and made by KDE which is Linux developers.
I’m pretty sure that a Celeron D is a 64 bit processor. Did we get confirmation on that?
