SSDs do have a limited life, the way they work means that they gradually lose capacity over time. They are designed to cope with that to a certain extent but they will not last as long as a cared for hard disk.
Lenovo have been in a bit of trouble recently for putting software on their machine that can be used to monetise their customers. You could call it spyware. And my wife's & daughter's Lenovos were forever losing screws from the bottom of the case.
Think about what you want the machine for, if you're only using the internet and writing letters you don't need as fast a machine as you'd need for graphic manipulation.
As others have said, it depends how your old machine died. If the hard disk was getting a bit dodgy you could revive it and get your data off using something like
this. I've used it on a number of machines and while it may take a while it is certainly effective.
BTW, my wife bought an HP to replace the Lenovo.
