My trusty Panasonic CF-W2 is now 5 years old and I am worried that the disk will give out any day (backing up frequently).  I tend to buy computers a bit ahead of the curve – even though that means paying up a bit – and then keep them until they start to fall apart.  My next machine will have a solid state drive for sure.  Finally no more moving parts and hopefully no more disk failures.  I am seriously considering switching to a Mac now that there is finally a lightweight machine.  I wish that Panasonic would offer the otherwise insanely awesome CF-W7 with a SSD.  I will also investigate the Lenovo X300.
