laptop advice

[the_ultimate_evil]

my current laptop is coming up to near 3 years old, but it's memory that worrys me most as i'm down to about 20 gb of a 100 gb memory

i know that still a good size but with working with large image and photographs i don't know how long it will last

i've been looking at this model HP G70-2112

* Intel Pentium Dual Core Processor T3400
* (2.16GHz, 1MB Cache)
* Genuine Windows Vista Home Premium
* 3GB Memory
* 250GB Hard Drive
* Lightscribe Super Multi DVD Writer
* 17" BrightView Screen
* Built-in webcam
* Wireless Enabled
* 5-in-1 cardreader

so has anyone any past experience with this laptop or what do you think. the cheapest i've seen it is around £420, i'm at the moment using a hp compaq v6000
