I have a Dell Vostro 1400 to sell after a variety of reasons I am going to go to a Mac (no comments :)
The specs are:
Intel Core 2 Duo T5470 1.6GHz (800MHz FSB)
2048MB RAM (Max 4GB)
Windows Vista Business
Inbuilt Multicard Reader
Wireless (it's centrino duo)
9 Cell Battery (can reach up to 3-7 hours on depending on usage. If you connect an external monitor and turn off the LCD it can reach up to 10 hours!)
Intel GMA X3100 (A very competent GPU)
Note: The below picture is to illustrate I do own the machine right now - Forgive the quality however am looking for my camera right now for some better shots) http://img125.imageshack.us/img125/2952/spa0817ua0.jpg
Flawless condition, Dell Warranty can be transferred to you.
I have an offer by a friend however am in truth wanting a bit more. Am looking for around £520 + Delivery. Offers welcome.
