Over-Priced: We fully understand the fact that it is SONY. But, paying so much for a device that performs so poorly does not make any sense
Super high resolution: What is the point of giving the user super high resolution in an 8-inch screen? Is SONY under some contract of putting so outrageous resolutions in small screens? Looks like they learned nothing from their UX series which squeezed 1024×600 pixels in an 4.3-inch display
HDD not easily upgradable: Although we do not upgrade the HDD everyday, but it should be easily swappable in case something goes wrong with the HDD or if the user wishes to use SSD
Poor performance by the entry level model: 1.33GHz simply chokes while running Vista
Even entry level model costs nearly twice as much as other netbooks in the market
Making the entry level model bundle with Windows Vista
Whole device is built around the keyboard and not anything else: I guess the engineers at SONY did not use the device for more than 5 minutes.
Trackball: Trackpad is the way to go.
Below-average or just average battery life with the standard battery: Even if the SONY is entering so late in the netbook market, it should have already made out that the people want netbooks with REALLY good battery life. Netbooks with 2-3 hours battery life are things of past now.
Do yourself a favour and get something on which you can really work upon.
