dear lovely desertnana,
If reading ebooks is a highly ranked criterion for your purchase (if not, disregard this opinion), I wouldn't recommend it... yet. At least that was the result after my search, just nothing perfect for me in the market atm.
As others in this thread have pointed out indirectly, netbooks simply aren't ergonomically designed for long reading sessions - whether it be glossy lcd screen, keyboard getting in your way, weight distribution of the machine, etc.
Well, if you do have a good tolerance of prolonged reading on lcd and if you can withstand other physical factors, never mind.
If I'd get one personally for reading, I would wait (ah, the gadget lover's dilemma) for the release of upcoming tablet/touchscreen netbooks...
Asus eee T91, or the widely rumoured Apple tablet, for example. Reading vertically w/o the keyboard getting in your way.
