My computer gets left on for long periods of time. It's currently been in on two days none-stop. Like an idiot, I put my K750i's memory stick (64MB) into the card clot and when I took it out it had melted (and I nearly burnt myself too).
So now I need a new one. I'd like to go for whichever one gives the best megabytes per £, e.g. £20 for 1GB is preferable compared to £11 for 512MB, but if 1GB was £25 I'd go for the 512MB if you understand that... bearing in mind that my phone will only take upto 1GB.
As always, karma to anyone who helps.
