In February, we reported that Galaxy Note probably would get the Ice Cream Sandwich (ICS, aka, Android 4.0) update in March (together with Galaxy SII).
Obviously, Samsung missed the target. Galaxy SII users in Europe and some other regions started to receive ICS update about two weeks ago. Nothing for Galaxy Note users.
Last week, Samsung officially pushed the date to Q2. So, your waiting time should vary from one week to one week plus 3 months. Usually, when a phone manufacturer tells in Q2, it usually means June; it seldom means April.
The good news is that Samsung will bundle the S-Pen “Premium Suite” Apps together with your delicious ICS. You may watch the preview video of this “Premium Suite” on Youtube. It is not so bad, anyway.
For those who 
Galaxy Note got a quite good review on performance, phone quality, 4G LTE connectivity, 5.3″ display, and the camera. The editor’s major concerns are: 1). the S pen is too small and 2). the size of this device may be awkwardly large for some people to fit into pocket.
The review is quite positive. The reviewer dived into some aspects that other reviewers overlooked, e.g., Samsung’s TouchWiz UI, S Memo. The reviewer’s major concern is the lack of apps for S Pen. Spot on. The conclusion is unique and impressive, but not for everyone.
