At $2 per GiB yes; but, at the current prices that is a definet no... laptop works just fine. Who would not like some extra speed, but not at 500 CAD for a 128 GiB SSD - don't consider 64 GiB SSD a practicle upgrade.
I'd get a 7200 RPM hard drive with more space for the laptop. At least when it finally gets to the point that I can no longer stand how slow the basic experience is I can turn it into a storage server.
Well... for $130 I can get a sweet 40Gb Intel SSD. So if I were to invest in a longer lifespan on my old laptop that would be it. Otherwise, that money may be better spent on a new nettop or entry level laptop. Am not really concerned with storage on a laptop/nettop since my desktop is my main PC and all my stuff is stored there. My nettop is mainly just for doing presentations for my business and only has a few docs and whatnot on it.
I believe at laptop prices nowdays SSD still makes no sense unless economically you can justify the upgrade IE.Autocad,rendering work,Gaming if thats ur thing,or any other way in which the ssd will proove itself usefull as for everyday normal people use i think not. SSDs will become chepaer and thus i will upgrde then but as to upgrade older machines i believe not. Im pretty sure my wife was better off getting a 500 dollar vaio with a Dual core CPU bigger HD and windows 7 than putting a ssd on her aging compaq with a pentium m and windows xp. Just my 2 cents
Windows XP + MS Office / OpenOffice = 5.5GB
Linux Mint + OpenOffice + GIMP + everything else that comes preinstalled = 4.5GB
So I can see using a 16GB SSD but my biggest problem with old laptops is the lack of RAM and poor battery life / battery life degradation. Add a new battery and a RAM upgrade and you might as well buy a new laptop with a faster processor, better screen, better power efficiency and a warranty.
