From the Cheapskate: Originally $700 (!), this 5.5-inch phone features an arched design and scratch-resistant coating.
Mail's memory footprint will depend on how you use it, but on average it should take up between around 50MB and 200MB of memory. For instance, I currently have 3746 messages in my in-box from 5 e-mail accounts (two Gmail accounts and three from other providers), as well as a few RSS feeds. With this setup on two machines Mail uses 104MB of RAM on my Snow Leopard machine, and 62MB on my Leopard machine. Some people, however, seem to run into problems where Mail will spike in RAM usage, resulting in system slowdowns.
The low-price PC seller's cheapest box now comes with a 2.5GHz Celeron, 256MB of RAM, a 40GB hard drive and a CD burner for $399 after a rebate.
