Purchasing a Old Laptop


Sep 4, 2013
hello everyone

I'm planning to buy an old laptop - basic use will be to use it for trading terminal (for stock) (java based trading terminal) + internet + might use it while travelling.

A lot of old models with different specs are available here. However, am a little confused as to which one should I buy.

What would you suggest from the following or something different which you think might suit my needs. Please also suggest which screen size I should buy since main aim is to use it for trading in stocks using the trading terminal.

- Core i7 with normal hdd (3/4 gen)
- Core i7 with SSD (1st gen)
- Core i5 with SSD (3/4 gen)
