I'm seriously considering picking up the 12.1'' Powerbook with a combo drive and the airport card. I noticed the buying guide says don't buy because updates are "coming soon." I have a few questions: 1. How long after Apple updates their product line are the old products still available? 2. I'm a bit wary of buying the first revision of a new product. The Titantium Powerbooks initially had that craptastic paint that came off, etc.. etc... Is it better to wait until the update after this forth coming update, in which case it would just be better to buy now? 3. Is it possible to buy the Airport extreme card from anyone other than apple? $89 for a internal 802.11g card is pretty steep. 4. I've been a long time windows guy, never really used an apple product unless I had to for a class. Now I'm considering picking one up for taking notes and such. Is there any reasons I should avoid buying the powerbook and get say a Dell laptop instead? 5. How critical is the applecare protection? 6. Does the Apple online store charge tax? I configured an entire machine yesterday, created an account, go all the way to the pay screen and saw _no_ mention what-so-ever of tax. I assume Apple can't charge my charge for more than I agree to, which doesn't include tax. Thanks!
