I'd been look to upgrade my laptop for a while I put the max ram in (4G) upgraded the HDD TO 500G the CPU runs at 2.1GHZ (Dual core)but the thing was getting sluggish did a fresh install of windows still sluggish, Most laptops in my price range had the same specs so I didn't want to spend money on getting the same! thought for ages should i get a SSD, thought I'd wait until the price gets near to HDD but I took the plunge, best investment I've made.
Did a fresh install of Windows 7, had a few problems with updates freezing, but what a difference it's like having a new faster laptop (Sata 2 not 3) boot up from cold less than 30 second, power down less than 10 seconds, Itunes in under 3 seconds, internet Pages load way faster. I also bought an HDD adaptor which slots into the DVD drive (I put my old laptop HDD in it (didn't really use the DVD drive but I have a USB one anyway) so I now have SSD running OS and programs and HDD running everything else.
I will get another one for my netbook
UPDATE...
bought another one £10 cheaper! off here,
used my Acer back-up disc and there was not much difference between HDD and SDD took all the bloatware out, still the same, a little bit faster but not much more, so I put a clean install of Windows 7 64bit hopping it would make a difference, well it did, big time, my netbook Acer 1.5G dual core, 2G ram runs really fast now (for a netbook)
A very good upgrade
