Netbook and Zenbook - Some Advice Needed

[ameerat42]

Background:
Netbook is compact and light - and slowww!
Zenbook is superfast but bigger.

Now the Netbook (ASUS EEE) has an Atom 1.6GHz CPU, 1 GB RAM, 160GB HDD (2x80GB partitions), and runs on Win & 7 Starter. It cost me $350, and it's been on 2 OS trips and is still good for modest tasks. But the HDDs are filling up and it is getting slowwweeerrr! So am wondering if it's worth:
1. whacking in a 240 GB SSD,
2. adding another GB RAM,
and thereby readying it for WIN 10 upgrade. Ie, would this work?

It gets a fair bit of use about the house as a 2nd machine... Well, when one can be bothered waiting for it to respond.
